    notes

    • A warm to hot discussion is performed in choosing Plotly.js over Chart.js for xy-scatter plot 1.
    • The plot can be responsive, which is hopefully suitable for smartphone screen 2.

      • Add (not working) on the title and rename the note file, move it from floating to flawed category.
      • The canvasplot.js does require d3.v3.min.js, but after some tweaks it can not render the grids on the axes area and data with markers still not shown, even after a long discussion and correction trials 1.
      • It can load d3.v7.min.js and canvasplot.js, and layout of elements is still from 25k08 on 22-nov-2025.
      • Previous version is no longer 25k08 , which is in in 25j61 .

        lost n overwhelmed

        Honesly, I do not know what to do. I am feeling lost and overhelmed. It is not because of the heavy workload of a task, but uncertain load peak of many tasks. All are not regulary updated, but when they are required to process, after triggered by other events, they are entering the queue and the energy to perform all of that is not sufficient. It might seem that I exaggerate it, or it is just because I am exhausted?

            • Rename this from “cmds for book terminal” to “cmds and shortcuts for book”.
            • How to update main repo and its submodules is still not fully understood 7.
            • The alternative subtree is also confusing 8.
            • There is no Backspace on macOS but Fn + Delete 9.

            • App window: Shift + Command (⌘) + 4, then press Spacebar.

                        first js in the train

                        It does not work well. The irregular oscillation makes me dizzy. Small font size in the computer screen also make it worse.

                        This test fails.

                        notes

                        fix npprel for zinking

                        File npprel.py in setup/npprel folder has additional lines as follow.

                        if rel_path == '.md':
                            rel_path = '_index.md'
                            folder_path = 'content/'
                        elif rel_path == 'zinking.md':
                            rel_path = '_index.md'
                            folder_path = 'content/zinking/'
                        

                        File npprel.html in layouts/shortcodes/card folder has additional lines as follow.

                          {{ if eq $cleanTitle "" }}
                            {{ $cleanTitle := index $parts 1 }}
                            <div class="title">{{ $cleanTitle }}</div>
                          {{ else }}
                            <div class="title">{{ $cleanTitle }}</div>
                          {{ end }}
                        

                        The card now can call npprel:// protocol to open file _index.md in content/folder/ folder, where folder can be any subfolder name.

                        • After a short discussion 1, the button is included in notes (posts) template instead of as a shortcode.
                        • For older notes without filetopath parameter in the front matter, the text with link will not be displayed.
                        • Rename filetopath to pathtofile on 14-oct-2025.

                            npprel problem

                            intro

                            • Content of setup/npprel/npprel.py is as follow.
                              import os, sys, subprocess, urllib.parse

                              # This script is in <repo>\setup\npprel\npprel.py
                              script_dir = os.path.dirname(os.path.abspath(__file__))
                              
                              # repo root is two levels up
                              repo_root = os.path.abspath(os.path.join(script_dir, os.pardir, os.pardir))
                              
                              if len(sys.argv) < 2:

                              url = sys.argv[1]  # e.g. npprel://content/post/my-post.md
                              parsed = urllib.parse.urlparse(url)
                              rel_path = urllib.parse.unquote(parsed.path).lstrip("/")

                                  folder_path = 'content/'
                              
                              full_path = os.path.normpath(os.path.join(repo_root, folder_path, rel_path))

                                  subprocess.run([NOTEPADPP, full_path])
                            • Problem:
                              • Link clicked does not open the Notepad++ with file nor only it when the file not exist.
                              • Commnd line does work, e.g. py npprel.py 25/h/62-categ-notes.md.
                            • Solution:
                              • Find Computer\HKEY_CURRENT_USER\Software\Classes\npprel\shell\open\command

                            • Discussion and instructions are availabe to read 2 and 3.
                            • It is observed on 24-oct-2025 that trigger action is still working but not directly activated after push. It requires about a minute or two to hapen. Cause is still unknown. Previously, it is called several times to activate it, which is actually simply the time required by the first call. Finally, tested on 0124 and observed on 0126.

                                    • Configure a NAT gateway in a public subnet.
                                    • Define a custom route table to the NAT gateway for intenat traffic.
                                    • Associate it with the private subnets for the application tier.
                                  • 02 To save cost for Amazon EC2 instances during a 2-week company shutdown.

                                    • Hibernate the instances before the 2-week company shutdown.
                                  • 03 Traffic direction to a standby EC2 instance if the application fails and becomes unreachable.
                                    • A secondary elastic network interface can be added to an EC2 instance.
                                    • While primary network interfaces cannot be detached from an instance, secondary network interfaces can be detached and attached to a different EC2 instance.
                                  • 04 A JavaScript script requirement in company users’ webpage, that makes authenticated GET requests to the company’s Amazon S3 bucket.

                                    • Use server-side encryption with customer-provided encryption keys (SSE-C).
                                    • Use client-side encryption to provide at-rest encryption.
                                  • 06 Anticipation to temporary increases in demand at the end of each month that will cause the job to run over the time limit but as cost-effectively as possible. The job is uniterruptable.
                                    • Deploy On-Demand Instances during periods of high demand.
                                    • Spot Instances: least costly option, but not suitable for uinterruptable job.
                                    • On-Demand Instances: billed for the number of seconds they are running.
                                  • 07 EC2 instances write the votes to an Amazon RDS database, but unable to keep up with the requests from it. Solution for most efficient manner and without downtime.
                                    • Configure the front-end application to send votes to an Amazon Simple Queue Service (Amazon SQS) queue.
                                    • Provision worker instances to read the SQS queue and write the vote information to the database.
                                    • It is a decouple the ingestion of votes from the database to allow the voting system to continue processing votes without waiting for the database writes.

                                  Click on npp:// protocol will call npp.bat that later launch Notepad++. First part of an URI, before the : character, is scheme, which indicates which protocol the browser must use to fetch the resource and it determines how the rest of the URI is structured and interpreted (MDN contributors, 2025). Suppose that you want to create a protocol that does something when the link is clicked, e.g. open a file with certain application, etc. There is straight forward information to create it in Windows by creating a reg file and import it to Windows registry (Tare, 2024). The idea is how to create a protocol that allows a link to a file, when it is clicked, it will launch Notepad++ to edit the file. There is a note (actually a Hugo post) about the process to get it works (Viridi, 2025). Brief steps and the requirements to create such protocol and use it in a Hugo post are given in this story.

                                  reg npprel-protocol

                                  Previous approach to launch a Hugo post via link in a HTML page hosted locally is still inconvenient due to absolute path to the file 1. Here better approach is reported as sugggested in a discussion with GPT-5 2. Steps to create own URL Protocol in Windows seems obvious 3, but not for me until today.

                                  demo

                                  As example edit this post. Click no the link edit will open Notepad++ editing the post.

                                  shortcode

                                  Content of link/npprel.html in layouts/shortcodes/ is as follow

                                  reg npp-protocol

                                  A Notepad++ launcher to make Hugo post editing easier is reported here. It uses a custom protocol and is informed to work on Windows 1, but unfortunatelly it does not. A lot of modifications are required to make it works 2. It also requires a shortcode to convert link provided in a Hugo post to the npp:// protocol 3.

                                  batch file

                                  Content of npp.bat located in C:\Tools is as follow.

                                  @echo off
                                  setlocal enabledelayedexpansion
                                  
                                  :: get the incoming URL (quoted)
                                  set "URL=%~1"
                                  
                                  :: remove npp:// from the front
                                  set "FILE=%URL:npp://=%"
                                  
                                  :: replace forward slashes with backslashes
                                  set "FILE=%FILE:/=\%"
                                  
                                  :: remove the first backslash
                                  for /f "tokens=1* delims=\" %%A in ("!FILE!") do (
                                      set "FILE=%%A%%B"
                                  )
                                  
                                  :: launch Notepad++ with the real path
                                  "C:\Program Files\Notepad++\notepad++.exe" "%FILE%"
                                  
                                  endlocal
                                  

                                  This batch file is required to strip npp://, convert / to \, and remove the first \. The protocol is only needed to identify the protocol but must not be passed. Link to file in HTML file is different than link used in Windows. The first \ will make the link relative to C:\Windows\System32\.

                                    one-dim collisions

                                    There are two schemes for collsion, which are hard-sphere and soft-sphere.

                                    hard-sphere scheme

                                    In collision with coefficient of restitution $e$

                                    $$ \tag{1} v_{1f} = \frac{ m_1 v_{1i} + m_2 v_{2i} + m_2 \ e (v_{2i} - v_{1i}) }{ m_1 + m_2 } $$

                                    gives final velocity of mass $m_1$ and

                                    $$ \tag{2} v_{2f} = \frac{ m_1 v_{1i} + m_2 v_{2i} + m_1 \ e (v_{1i} - v_{2i}) }{ m_1 + m_2 } $$

                                        • There are still not any workarounds for styling a subgraph using classDef 1.
                                        • Until now there is no available Mermaid colour scheme baked into Hugo/Chroma the way there are for mainstream languages 2.
                                        • Some Mermaid keywords and values can be colored differently in render-codeblock-mermaid.html 3.
                                        • This will used in other notes, e.g. 25i20 .

                                          This isn’t really a story so much as a handful of images — a quiet record of where my pepper plant has ended up. :-)

                                          Unplanned planting

                                          It’s been growing for months now, though I honestly can’t recall exactly when it first appeared as a seedling. What I do remember is that it wasn’t planned at all. It sprouted by accident, tucked into a bit of soil where I hadn’t expected anything, and instead of pulling it out, I decided to keep it. Since then, I’ve just let it grow at its own pace, watching it change little by little. There’s something grounding about that — a small reminder that not everything needs planning to have meaning.

                                          It is already a year after the last installation, which it was at the beginning of the year 2024 (Viridi, 2024). And I do not remember when I uninstalled it. Today, after I can not align grouped objects in Word, which was worked previously (GPT-4, 2025), Inkscape will be reinstalled. This story is about it.

                                                  It is the first time I read about Nyquist plot and then discuss with GPT-5. Previously I just discuss with GPT-4 after informed by Widiatmoko and then Aditya.

                                                  • Electrochemical Impedance Spectroscopy (EIS) is an AC technique that measures the response of an electrochemical system to a small sinusoidal perturbation over a wide frequency range to analyze charge transfer, mass transport, and other electrical contributions 1.
                                                  • The Nyquist plot, which displays the imaginary versus real components of impedance, is commonly used in EIS to reveal characteristic patterns that aid in interpreting electrochemical processes 2.
                                                  • As an example, in a study EIS Nyquist analysis was used, where the high-frequency region revealed the charge transfer resistance while the low-frequency region reflected the capacitive response of the system 3.
                                                  • A tutorial illustrating Nyquist and Bode plots for electrical circuits containing single passive elements (R, C, or L) and their series or parallel combinations is available 4.

After choose two initial guesses a line is formed using the two-point form of the line and by setting $y = 0$ an iterative formula is obtained (Weisstein, 2023). It can be considered as one of the attempts to speed up the bisection method (Tyagi, 2022) but it might be less precise than bisection method (itskawal2000, 2021). This method has been generalized for finding both zeros and extrema of a function (Gomes & Morgado, 2013).

Since this method retains only the most recent estimate, the root does not necessary bracketed (Weisstein). Because of that secant method may not converge (Han, 2017). There is a report explaining origin and evolution of secont method in 1-d (Papakonstantinou & Tapia, 2013).

It is one of the most widely used methods for root finding and it can be shown that this technique is quadratically convergent as the root aproached (Smith, 1998). This algorithm is quite versatile with wide-ranging use cases than span many domains, e.g by reframing the function of interest for the value of $x$ that yields a certain value rather than being restricted to $0$ can be searched (Dolphin, 2022). There is a report about historical development of this method (Ypma, 1995), where there are differences between this technique and Newton’s technique (Nadhim & Al-Jilawi, 2022).

                                                                                                                                                                                                                                                      • There two types of argument passed to function in Python, which are positional and keyword arguments (Wilkinson, 2023).

                                                                                                                                                                                                                                                      • Due tue not aware of all possible use cases of a code, and to offer more options for future programmers working with the module or for users interacting with the code, passing a variable number of arguments to a function can be accomodate using *args and **kwargs (Tagliaferri, 2021).
                                                                                                                                                                                                                                                      • In the Python documentation about its functions it is common to see *args and **args defined as parameters in some functions, which is a major cause of confusion for most Python programmers (Pykes, 2022).

It is a typical solution in optics if met the physical limit of a resolution (Rom39, 2015).

One way to represent the palette in the form of color grid (Chakraborty, 2018). Here we will not make such color grid, but more like combination of only of two colors, i.e. black and white, in a grid for certain proportion of grid in white and black.

It has default style, which should be sufficient. But if an adjustment is necessary, e.g. style of the link – the line connecting two nodes, can be modified (Drago, 2023) and also the other features.

This method uses the intermediate value theorem iteratively to find roots (Kong et al., 2020). It is also known as the interval halving method, where it provides a systematic approach to finding the root of a function within a given interval (Collimator, 2023). A brief about this method and JavaScript code are given here.

                                                                                                                                                                                                                                                        • It is a number which is generated for, or part of, a set exhibiting statistical randomness, where the statistical randomness is a characteristic where a numeric sequence is said to be statistically random when it contains no recognisable patterns or regularities ( WHS, 2021 ).
                                                                                                                                                                                                                                                        • A random number is a number chosen as if by chance from some specified distribution such that selection of a large set of these numbers reproduces the underlying distribution and almost always, such numbers are also required to be independent, so that there are no correlations between successive numbers ( Weisstein, 2023 ).

                                                                                                                                                                                                                                                                • It is a shorthand representation of the data which they refer, or when use analogies, it is reference to data ( ODS, 2016 ).

                                                                                                                                                                                                                                                                • Metadata is data that describes other data and digital files often include metadata to provide information about the file and its contents as in digital image and document files ( Pickle, 2022 ).

                                                                                                                                                                                                                                                                • The <g> element groups all of its decendants in one group, which makes it is easy to add styles, transformation, interactivity, and even animations to the entire group of objects ( Soueidan, 2014 ).
                                                                                                                                                                                                                                                                • Transformation applied to the <g> element are also performed on its child elements, and its attributes are inherited by its children, including core, styling, conditional, and presentation attributes ( taran910, 2022 ).
                                                                                                                                                                                                                                                                • With <g> element the grouped elements can be reused as if they were a single element, that is an advantage compared to a nested <svg> element which cannot be the target of transformation itself ( Jenkov, 2014 ).
                                                                                                                                                                                                                                                                • It can also group multiple elements to be referenced later with the <use> element ( MDN, 2023 ) and can apply the same style to a set of elements ( LeBeau, 2013 ).

                                                                                                                                                                                                                                                                introduction

                                                                                                                                                                                                                                                                • SVG element in a HTML page can be created dynamically using JavaScript and customized its sub-elements, which is a little bit different than in createing HTML element since SVG is described in XML ( Quante, 2021 ).
                                                                                                                                                                                                                                                                • Using only pure JavaScript or known as Vanilla JavaScript, without help from any JS libraries or frameworks, SVG elements can be created and manipulated easily but with slightly different way than in handling HTML elemements, e.g. it is used createElementNS instead of just createElement ( Katz, 2021 ).
                                                                                                                                                                                                                                                                • Pablo, as a lightweight, open source library, can be used for this purpose, since it is simplifying the construction and manipulation of SVGs in JavaScript, that enables developers to more easily work with dynamically generated vector graphics while avoiding the verbose workflow of vanilla JavaScript ( Omotayo, 2022 ).

                                                                                                                                                                                                                                                                animation

                                                                                                                                                                                                                                                                • An animated watch can be built with SVG tags by typing them manually inline in a HTML file and then animated using JavaScript ( Borbély, 2021 ).
                                                                                                                                                                                                                                                                • Animation of SVG elements triggered by user interaction can also be built from primitive shapes and then animated using JS with the help of JS library, e.g. Pablo, where the event detection and handler are easy to implement ( Omotayo, 2022 ).
                                                                                                                                                                                                                                                                • Similar dynamic SVG elements can also provided using JS library designed in supporting animation, e.g. GSAP ( Roblewsky, 2020 ).

It can also considered as a compact but general way to represent any linear transforms, such as rotations, scallings, projections that map points / lines / planes to point / lines / planes ( user65203, 2018 ). The concept of matrix overlaps in the fields of mathematics and computer science, where elements represent data or mathematical equations, which are used as a way of providing quick approximations of more complicated calculations since they can offer accurate and quick calculations used to better control an operation regarding as a mechanical device or a computer ( Monitor, 2023 ). Here how to define matrix and apply some simple operations to them in Python are presented.

Here illustrations how to obtain the formulas are given.

Then integral of any polynomial is simply sum of the integrals of its tems, whose formula of its indefinite integral is well known ( Nave, 2017 ) and its definite integral can be calculated with the help of the formula, e.g. using Python ( Mehta, 2021 ). Simpson’s rule can calculate integral of polynomial function by approxymating it with set of quadratic functions ( Kong et al., 2020 ), but not recommended since it is not very efficient compared to the use of its indefinite integral formula.

By following some suggested guidelines and avoiding common errors, even novice authors can make the publication process streamlined and success ( Hoogenboom & Manske, 2012 ). To make it more structured universities provide science writing course, such as in Standford university, Nature Research, Moscow Institute of Physics and Technology, Duke university, and a scientist personal site ( Clippings.me, 2019 ). And in Institut Teknologi Bandung, there is NT6094 Scientific Journal Writing for guiding graduate students in publishing their work.

This programming language provides a different method of coding, instead of high level statements in procedural and object-oriented languages, it is coded by selecting objects, connecting them, and adding functionality ( Christiano, 2015 ). This type of language can be designed to support only specific purpose, such as for Insect Intelligent Building platform ( Chen et al., 2020 ).

One way to study it is by performing various simple experiments ( Carolina, 2010 ). Estimating motion of vehicles at intersections is one of kinematics application ( Ahn & Kim, 2008 ).

Or it can be said that vector and scalar quantities are the types of physical quantities that are used in physics ( Tutorialspoint, 2022 ). Before jump to the definitions, let discuss in brief about what the difference between displacement and distance. The fact that displacement is defined by both direction and magnitude, while distance is defined only by magnitude, explains why displacement is an example of a vector quantity, while distance is an example of scalar quantity ( OpenStax, 2022 ). A short introduction of scalar and vector quantities with example s are given here.

                                                                                                                                                                                                                                                                  position to velocity to acceleration

                                                                                                                                                                                                                                                                  Essence of calculus is derivative, that is the instantaneous rate of change of a function with respect to one of its variables, which is equivalent to finding the slope of the tangent line to the function at a point ( Watkins et al., 1999 ). Position, change of position, and various rates of change of position are referred as kinematic variables, where the terms kinematics means the study of motion, from the Greek word for movement, kinesis ( Redish, 2019 ). If position is something as function of time, the first derivative gives its velocity, and the second derivative gives its acceleration, or simply differentiate position to get velocity and further differentiate velocity to get acceleration ( Zegarelli, 2021 ), where the derivative means derivative with respect to time.

                                                                                                                                                                                                                                                                  In many daily situations we can see parabolic motion, which is involving many factors such as gravity, velocity, acceleration, and time, where mathematics puts all in formulas explaining how it is formed and and continues ( Lincoln, 2020 ). Two laws must be known in order to derive the parabolic trajectory of the motion, where one is the law of free fall and the other is restricted principle of inertia, as Galileo discovered the motion as a case of serendipity ( Drake & MacLachlan, 1975 ). Two of features that are sometimes dicussed from the motion are maximum height and range ( Boundless, 2018 ). There are animation showing the superposition of uniform and non-uniform linear motions ( Henderson, 2022 ), calculator to find maximum height and range accompanied with their times ( Had2Know, 2023 ), and interactive visualisation with adjustable parameters to show the influence of factors to the trajectory ( Desmos, 2023 ). And it is also interesting that there is observation of perceptual judgments of duraction of parabolic motions in virtual reality world ( Jörges et al., 2021 ). Sometimes it is assumed to be the same as free fall motion ( Kumar, 2015 ), which is actually not ( Albert, 2023 ). Here equation of trajectory, usually as y = f(x), is derived from two parametric equations representing uniform linear motion in x direction and non-uniform linear motion in y direction.

                                                                                                                                                                                                                                                                  Relative position of an object is position of the object measured relatively from other object, which simply substraction of the object position and other object position ( Smith, 2012 ). Numerical calculation in solving physics problem is recommended, because the difficulty faced by the students will be a valuable experience in advancing their understanding and skill ( Allain, 2017 ). Here illustration about relative position is given and it is also accompanied with a numerical example.

And as the main reference it uses the textbook Principle of Physics, 10th Edition International Student Version with about 1320 pages ( Halliday et al., 2014 ). A draft of week plan is available ( Mahardika et al., 2023 ) and there are also some slides for personal use from a physics professor ( Iskandar, 2022 ). Then, even that you are working with a 15-week semester, there is another approach by designing a 12-week plan ( Talbert, 2022 ).

Sistem pada keadaan ini dapat dicapai bila tidak ada gaya yang bekerja pada pada sistem sebagaimana menurut hukum pertama Newton dan kecepatan awal sistem tidak nol ( Britannica, 2017 ). GLB secara umum dapat teramati pada kegiatan sehari-hari seperti kendaraan bergerak, benda di atas ban berjalan, dan lain-lain.

Terdapat berbagai bentuk bangun datar ( Utami & Nailufar, 2022 ), yang salah satunya adalah lingkaran. Lintasan melingkar merupakan kurva yang melingkupi lingkaran. Kurva ini dapat dinyatakan dengan beberapa bentuk persamaan lingkaran ( Turito, 2022 ). Selain terkait dengan kinematika gerak melingkar ( Wikipedia, 2023 ), lintasan melingkar yang merupakan bagian dari pola-pola Lissajous, dapat pula diperoleh dari superposisi dua gerak harmonis sederhana ( Electrical4U, 2020 ). Bagaimana lintasan berbentuk lingkaran dapat diperoleh dari gerak harmonis sederhana (GHS) atau simple harmonic motion (SHO) akan disinggung di sini.

Diantaranya pendidik meminimalkan peran sebagai learning material provider, pendidik menjadi penginspirasi bagi tumbuhnya kreativitas peserta didik. Sehingga terjadi perubahan cara belajar oleh peserta didik dan cara mengajar oleh pendidik.

Sebelum mengenal DEM, simulasi dengan menggunakan MD telah dibuat dengan frontend JavaScript [ 3 ] dan mulai dikembangkan dengan Python [ 4 ]. Sebagai sebuah puncak, suatu karya Q1 telah berhasil dihasilkan oleh Fenfen Fenda Florena [ 5 ] dengan menggunakan DEM bersumber terbuka Yade [ 6 ], yang sempat membuat goyah apakah harus tetap mengembangkan piranti lunak sendiri? Tulisan ini akan menjadi pengingat bahwa untuk tetap konsisten untuk impian awal untuk memiliki suatu karya sendiri untuk bidang granular dengan nama yang orisinil, butiran.

Pemateri bertempat tinggal jauh Soppeng [ 4 ], yang menurut penuturannya melalui pembimbing sulit mendapatkan sinyal yang baik untuk akses internet. Layanan Zoom bebas sempat terputus dan disambung lagi dengan tautan yang sama [ 3 ].

Aturan pra-syarat kuliah ini dapat diatur dalam sistem LMS untuk satu kuliah atau rangkaian kuliah [ 2 ].

Kedua kuliah ini pun memiliki pra-syarat juga, sehingga memang perlu merancang dengan baik rangkaian kuliah untuk mengambil FI4171.

Selain terdapat berbagai kelebihan format citra SVG seperti scalability dan ukuran yang kompak [ 3 ], terdapat juga beberapa kekurangannya seperti ukuran berkas akan bertambah dengan cepat bila obyek terdiri dari banyak elemen kecil [ 4 ]. Secara umum citra berformat SVG merupakan kode sehingga ideal untuk animasi dan dapat dimanipulasi dengan CSS atau JS, yang sayangnya perlu terdapat upaya lebih untuk mempelajari makna dibalik kode tersebut [ 5 ]. Secara umum SVG ideal untuk menampilkan logo, ikon, dan desain geometris vektor lainnya, yang digunakan untuk elemen grafis yang akan ditampilkan dalam berbagai ukuran pada berbagai devais, serta perlu untuk diperbarui dan disunting [ 6 ].

Kata kunci yang belum diperoleh ‘Julu’ (sudah ketinggalan tiga versi dari yang dipelajari kolega), mungkin terkait dengan data citra CCTV dan satelit untuk pengamatan tinggi air di dalam kawah gunung Kelud, dan belum dicari ‘Julian’ (disarankan kolega dari kolega yang bekerja pada pabrik pembuat semikonduktor untuk mengolah data banyak real time dari berbagai sensor).

Telah dibicarakan akan tetapi belum dapat dilaksanakan karena satu dan lain hal. Mungkin perlu didalami bagaimana sebenarnya melakukan kolaborasi dalam orginasasi [ 1 ], bagaimana mencari kaitan kemampuan antar bidang dengan analisis jaringan [ 2 ], dan bagaimana kolega dalam bidang berbeda dapat berkomunikasi dengan istilah yang sama [ 3 ].

Terdapat tiga topik yang diusulkan. Salah satu tidak dapat hadir akan tetapi telah membicarakan bahwa akan mengerjakannya bersama-sama. Mungkin ada pembagian antara eksperimen sederhana dan simulasi.

Dalam rentang waktu yang lebih lebar parameter cuaca seperti temperatur memiliki pola berulang dalam satu tahun sehingga secara umum dapat diprediksi [ 2 ]. Walaupun para fisikawan mendefisikan iklim sebagai suatu sistem kompleks, yang tidak dapat diselesaikan secara analitik, akan tetapi dengan perkembangan komputasi pada tahun-tahun belakangan ini, terdapat sejumlah algoritma numerik untuk menyelesaikan, dengan algoritma pembelajaran mesin (Machine Learning algorithms) merupakan bagian dari algoritma-algoritma tersebut [ 3 ]. Di sini hanya akan disajikan analisis sederhana yang belum memperkirakan cuaca di kemudian waktu.

Sesuatu yang perlu dikeluarkan agar usaya dapat berjalan dapat dibedakan menjadi biaya dan pengeluaran, yang agak berbeda penggunaannya pada bisnis dan akutansi [ 3 ]. Laba, yang dapat disebut juga keuntungan dalam batas-batas tertentu [ 4 ], diperoleh dengan mengurangkan total penghasilan dengan total pengeluaran. Pada contoh-contoh sederhana di sini hanya digunakan istilah penghasilan, pengeluaran, dan keuntungan.

Di sini akan coba disinggung penyelesaiannya secara matematika disertai dengan penjelasan untuk dua macam terlebih dahulu.

Dengan demikian terdapat antara 9000 dan 10000 kombinasi yang mungkin. Di sin akan didiskusikan hanya bilangan yang bernilai antara 1000 dan 9999.

Sayangnya terlalu banyak buku, akan tetapi terlalu sedikit waktu untuk dapat membacanya [ 2 ]. Untuk itulah terdapat bebagai daftar buku-buku yang perlu dibaca, dan salah satunya disusun berdasarkan suasana hati dan minat [ 3 ]. Seorang tokoh, Elon Musk, merekomendasikan sebuah daftar bacaan yang mungkin dapat mengubah hidup seseorang [ 4 ]. Untuk itulah halaman berisikan daftar buku, yang informasinya diperoleh dari media soal, dibuat untuk mengingatkan terdapatnya buku-buku atau media cetak lainnya yang mungkin menarik untuk dibaca. Tanda ✔ akan diberikan untuk buku-buku yang sudah dibaca dan menarik untuk dikaji lebih lanjut dan ✖ untuk yang sekedar telah dibaca. Bahan bacaan juga diperluas ke multimedia seperti audio dan video.

Saat setelah reparasi selesai sempat datang ketua UKA dari lab yang dikunjungi dan diberikan pengarahan agar melakukan perencanaan dengan baik ke depannya.

                                                                                                                                                                                                                                                                    summaries

                                                                                                                                                                                                                                                                    • Kecepatan jaringan kampus telah mencapai 8 Gpbs yang tidak terdukung oleh beberapa router dan switch di unit yang masih hanya sampai 100 Mbps, penggantian dapat dilaksanakan tahap per tahap dengan merencanakan, mengganggarkan, dan sampai memantau proses pengajuan sampai penerapannya.
                                                                                                                                                                                                                                                                    • Hotspot Eduroam yang saat ini berjumlah tujuh titik masih dirasakan kurang, akan tetapi untuk menambahkannya memerlukan piranti keras yang tergolong cukup mahal sehingga perlu dipertimbangkan dengan lebih matang, mengingat tujuan Eduroam lebih kepada komunitas riset dan edukasi international [ 3 ], misalnya peneliti, dosen, mahasiswa tamu internasional.
                                                                                                                                                                                                                                                                    • Adalah baik terdapat beberapa alternatif koneksi, yaitu jaringan kampus dan titik-titik hotspotnya serta hotspot Eduroam, sehingga memastikan bahwa koneksi internet tetap diperoleh oleh sivitas akademika, akan tetapi perlu dicari optimasinya karena merawat lebih dari dua jaringan (jaringan kampus perlu dirawat lokal, sedangkan Eduroam langsung dari DSTI) memerlukan upaya lebih ketimbang hanya satu.
                                                                                                                                                                                                                                                                    • Pelabelan perlu dilanjutkan sehingga mudah untuk melacak bila terdapat masalah di kemudian hari, yang dapat dilakukan dengan mencabut kabel lalu memeriksa target komputer yang tidak terkoneksi, di mana kegiatan perlu disosialisasikan sehingga tim jaringan perlu berkoordinasi dengan K3G sehingga mendapatkan akses ke ruang-ruang pengajar setelah sebelumnya mendapatkan ijin.
                                                                                                                                                                                                                                                                    • Penarikan kabel dari router / switch setelah FO ke komputer sivitas akademika dianjurkan bila masih terdapat port kosong untuk memudahkan telusur masalah ketimbang terdapat hirarki jaringan yang membuat semakin kompleks dengan adanya layer-layer core, distribution dan access [ 4 ].
                                                                                                                                                                                                                                                                    • Terdapat server lab yang memiliki IP statis dan komputer lain untuk keperluan akses dari luar kampus atau LN untuk tunneling tanpa menggunakan VPN kampus, di mana hal ini sebaiknya tercapat dengan baik sehingga bila suatu saat terdapat kebocoran keamanan atau serangan ke jaringan, pengelola DSTI dapat diminta bantuannya. Juga disarakan agar komputer-komputer dengan IP statis tersebut dimintakan melaluti tiket DSTI agar dikeluarkan dari daftar IP yang disuguhkan ke suatu komputer saat menyala dengan konfigurasi DHCP (konfigurasi yang disarankan oleh kampus).
                                                                                                                                                                                                                                                                    • Perawatan jaringan mungkin dapat dibedakan dalam setidaknya tiga bagian: (i) kampus sampai FO ke unit, (ii) di dalam unit sampai ke komputer sivitas akademika, (iii) lab-lab khusus yang memiliki server, komputer penelitian, dengan konfigurasi sendiri dan IP statis. Tanggung jawab (i) ada di DSTI, (ii) admin unit, dan (iii) pada admin lab yang berkoordinasi dengan admin unit. Dengan ini diharapkan admin unit tidak terbebani perawatan khusus lab yang cenderung tidak umum, kompleks, dan amat customized.
                                                                                                                                                                                                                                                                    • Terdapat tawaran layanan dari DSTI mulai colocation server, private cloud, dan virtual private server [ 5 ] yang memiliki kelebihan dan kekurangan dibandingkan dengan merawat sendiri server dalam lingkungan unit atau lab penelitian. Mungkin perlu dilakukan pencarian informasi lebih lanjut mengenai hal ini untuk mencari solusi yang lebih optimal bila dirasakan merawat server secara lokal unit memberatkan.
                                                                                                                                                                                                                                                                    • Terdapat pembicaraan bahwa admin jaringan merupakan pegawai DSTI yang diperbantukan di unit akan tetapi hal ini belum ditindaklanjuti. Bila sampai terjadi maka koordinasi pengelolaan jaringan akan menjadi lebih seragam dan terstruktur karena admin unit memiliki pemahaman yang setara dan sinergis dengan kebijakan DSTI yang mewakili kebijakan kampus.
                                                                                                                                                                                                                                                                    • Ke depan, dengan kebijakan yang masih dirancang, penambahan hotspot, komputer ber-IP statis, dan hal-hal lain yang dapat mengganggu kinerja jaringan, akan secara otomatis diblok dari piranti keras pas setelah FO dari kampus, sehingga perlu dilakukan perijinan terlebih dahulu dengan sepengetahuan admin jaringan unit kerja, baik prodi maupun F/S.
                                                                                                                                                                                                                                                                    • Terdapat pengarahan dari Dekan, yang kebetulan berkunjung saat akhir kegiatan dengan DSTI, agar rencana-rencana (pemutakhiran router lama secara per tahap, pengubahan topologi jaringan, penempatan hotspot-hotspot, alur pendaftaran devais baru dan kebutuhan IP-nya, form registrasi, perawatan piranti lunak terkait jaringan sivitas akademika sehingga tidak membebani jaringan, sosialisasi kebijakan terkait jaringan, pelatihan sederhana troubleshooting sehingga mendukung admin jaringan, pemutahiran komputer sivitas akademikia secara berkala-terkendali-sesuai-prioritas, dan lain-lain) dimatangkan, lalu disampaikan ke fakultas melalui prodi, dengan telah mendapatkan rekomendasi teknis dari DSTI dan UPT Pengadaaan.
                                                                                                                                                                                                                                                                    • Permintaan troubleshooting jaringan Lab Komputasi Lanjut dan di sekitarnya diminta pada 8 Juni 2022 dan selesai hari ini 7 Juli 2022, sehingga memakan waktu satu bulan karena satu dan lain hal. Masalah utama adalah koordinasi dan komunikasi. Hal ini perlu diperbaiki dengan mendokumentasikan langkah-langkah penyelesaian yang pernah berhasil.

It was Monday, 20 June 2022 about 1234 GMT+07, there is an offer about summer course online related to Food and Pharmaceutical Science College with target of 100 college students (ASEAN, will get SKPI), where the thema is Food Science and Technology China, where each lecturer or instructor will delivery materials in English about 60-90 minutes. There is an information related to SKPI [ 2 ], which will be given to participants of the event.

Sebagai suatu piranti lunak penangkap kuliah, Panopto menginjinkan pengguna untuk menyisipkan video, audio, tangkapan layar, dan slide ke dalam rekaman, sehingga semua tingkatan pengguna, fakultas, staf, mahasiswa, dari institusi pelanggan dapat membuat dan membagi rekaman pada Panopto [ 3 ]. Tersirat arti terkait dengan konsep pengawasan untuk kendali dan disiplin dalam nama Panopto [ 4 ]. Setidaknya terdapat sekitar 761 perusahaan yang menggunakan Panopto, di mana sebagian besarnya berada di USA dan dalam industri pendidikan tinggi [ 5 ].

Mermaid menggambarkan diagram alir dan grafik berbasis SVG menggunakan bentuk Markdown [ 2 ]. Menggambar di IPython Notebook agar hasilnya dapat dilihat saat berkasnya diunggah ke GitHub salah satunya adalah dengan menggunakan Matplotlib, di mana gambar dengan Matplotlib ini juga dapat disimpan juga dalam format SVG [ 3 ]. Untuk menggambar bentuk-bentuk yang lebih bebas dengan SVG dengan Python dapat digunakan paket PyCairo [ 4 ], yang saat digunakan dalam IPython Notebook menghasilkan berkas dalam format PNG agar dapat terlihat hasilnya di nbviewer [ 5 ], atau dapat pula dengan menyimpan hasilnya dalam format PNG dan SVG menggunakan inline display, yang sayangnya masih terdapat catatan bahwa hasil render SVG tidak didukung pada tempat yang sama [ 6 ], suatu informasi yang belum dipahami. Ada juga cara lain dengan menggunakan fungsi BytesIO [ 7 ]. Perlu dicoba untuk melihat pendekatan mana yang membuat hasil penggambarkan dengan format SVG dapat terlihat pada berkas yang diunggah ke GitHub. Hal ini yang menjadi tujuan tulisan ini.

ISCS merupakan suatu kegiatan rutin joint conference antara ITB dan KU yang sayang kurang terdokumentasi dengan baik [ 2 ], dengan pihak ITB diwakili oleh Program Studi Magister Sains Komputasi [ 3 ]. Saat ini akreditasi Prodi MSK dilakukan oleh LAMSAMA [ 4 ].

And the creepy story will be documented here, since it is too much to handle that as a separate repository.

                                                                                                                                                                                                                                                                      Tulisan ini mungkin dapat disebut sebagai tutorial untuk membuat situs web dari suatu repositori di GitHub dengan hanya menggunakan Markdown dan merupakan kelanjutan dari tulisan lain [ 1 ].

                                                                                                                                                                                                                                                                      Markdown membantu dalam membuat dokumen dalam teks polos (plain text) dengan suatu struktur eksplisit menggunakan hanya sedikit simbol tambahan dari yang digunakan untuk menuliskan isi dokument [ 2 ]. Bahasa markup ringan (light-weight) ini merupakan suatu kompromi antara menggunakan peyunting teks WYSIWYG (what you see is what you get) yang amat membatasi dengan memformat langsung isi dokumen dalam HTML [ 3 ]. Dokumentasi panduan programer dapat distandarkan pada Markdown seperti yang dilakukan dalam pengembangan iTwin.js [ 4 ]. Selain itu, bahasa markup ini juga digunakan di berbagai platform pengembangan piranti lunak dan forum diskusi daring [ 5 ].

Di sini akan disajikan informasi pembuatan situs web di GitHub tanpa menggunakan aplikasi GitHub Desktop [ 1 ], aplikasi pembuat situs web secara daring [ 2 ], aplikasi command line Git [ 3 ], ataupun tidak dengan melakukan clone repositori terkait [ 4 ]. Kegiatan dilakukan secara daring, hanya pada situs web GitHub, dan cukup berbekal penjelajah web seperti Google Chrome.

That is the only reason why this post is created, so the symbols can be copied from this post and then pasted to a text in Inkscape.

Lebih jauh teramati pula bahwa dengan gelombang yang sama akan tetapi benda berbentuk bola dengan karakter yang berbeda akan bergerak dengan laju yang berbeda sehingga terjadi proses segregasi yang diduga dapat dimanfaatkan untuk memisahkan polutan padat yang mengapung [ 4 ]. Bola-bola dengan ukuran yang sama cenderung berkumpul dan membentuk struktur hexagonal close packed dengan konfigurasi awal bujursangkar yang diganggu oleh gelombang kecil [ 5 ]. Beberapa bola yang terkoneksi dengan penghubungnya merupakan pembangkit listrik dari teregang atau terkompres telah disimulasikan sebagai suatu model sistem pembangkit energi listrik dari gelombang permukaan air [ 6 ]. Belum memahami bagaimana cara mengubah amplitudo gelombang.

Selain itu terdapat pula tes-tes lain seperti GRE, GMAT, LSAT, MCAT, MAT, TOEFL, and IELTS [ 2 ]. Terdapat pula pengulasan portofolio sebagai alternatif untuk GRE [ 3 ]. Untuk di Indonesia, secara umum TPA dapat dikatakan mirip dengan GRE [ 4 , 5 ]. Terdapat lembaga yang bergelut khusus dengan tes semacam ini seperti Tes Potensi Dasar Akademik (TPDA) atau Tes Kemampuan Dasar Akademik (TKDA), yang diperlukan bagi seseorang untuk dapat menyelesaikan studi di lingkungan pendidikan tinggi [ 6 ]. Perguruan Tinggi juga dapat menyelenggarakan tes serupa seperti Ujian Potensi Dasar Akademik atau UPDA [ 7 ].

Node.js yang bukan merupakan framework ataupun bahasa pemrograman sebagaimana kebanyakan orang salah mengerti dan memahaminya, sering digunakan untuk membuat layanan back-end dan karena menggunakan JavaScript memudahkan programmer yang sudah terbiasa menggembangkan aplikasi front-end dengan JavaScript untuk beralih ke mengembangkan aplikasi dengan platform ini [ 3 ]. Disamping terdapat keuntungan menggunakan Node.js terdapat pula kekurangannya yang perlu diperhatikan dalam pengembangan aplikasi [ 4 ]. Setelah melakukan instalasi Node.js suatu web server dapat dengan mudah dibangun [ 5 ], yang akan disinggung dengan singkat di sini.

Antara kedua benda yang berinteraksi muncul gaya yang berlangsung dalam waktu yang relatif singkat [ 2 ]. Untuk tumbukan 1-d terdapat beberapa kasus yang bergantung pada massa proyektil dan targetnya [ 3 ], di mana proyektil adalah benda yang menumbuk dan target adalah benda yang ditumbuk.

Rentang waktu antara dua kejadian akan berubah dalam suatu transformasi Lorentz yang berbeda dengan dalam transformasi Galilean, akan tetapi bila laju kerangka bergerak jauh lebih kecil dari laju cahaya dalam vakum, transformasi Lorentz dapat didekati dengan transformasi Galilean dan rentang waktu antara dua kejadian menjadi sama pada kedua kerangka [ 2 ]. Transformasi Lorentz secara formal mengekspresikan konsep relatif bahwa ruang dan waktu tidak absolut, bahwa panjang, waktu, dan massa bergantung dari gerak relatif antara para pengamat [ 3 ].

Pada efek fotolistrik energi foton yang diberikan pada elektron dalam bahan digunakan untuk melawan fungsi kerja bahan [ 2 ] dan di sini berlaku juga hukum kekekalan energi [ 3 ]. Dalam fisika moderen terdapat dualitas gelombang-partikel [ 4 ]. Pada hamburan Compton cahaya bersifat sebagai partikel karena memiliki momentum, dan terapat visualisasinya [ 5 ]. Pada eksperimen Davisson-Germer elektron memiliki sifat sebagai gelombang, yang dapat memberikan pola-pola difraksi saat dihamburkan pada bahan [ 6 ].

Sebelum membawanya untuk direparasi telah diduga bahwa penyebabnya adalah kerusakan pada sikring termal [ 3 ] dan ternyata benar. Setelah penggantian sikring termal selesai dikerjakan, yang dilakukn dengan memotong satu ujung yang tertambat dan menarik paksa las titik ujung lainnya, pereparasi tidak mau mendengarkan informasi bagaimana koneksi kabel-kabel semula terlihat saat perangkat dibongkar dan ia memasangnya dengan yakin karena saat diuji alat dapat menghasilkan panas, akan tapi tidak menunggu sampai sistem kendali panasnya bekerja. Akhirnya perlu dilakukan koreksi pada hasil reparasi dan perangkat kembali berfungsi dengan baik. Besoknya baru diketahui bahwa terdapat tutorial mengenai hal ini [ 4 ] untuk jenis perangkat yang tidak persis sama.

Tone.js membuat bekerja dengan We Audio API menjadi lebih mudah karena ia mengambil alih banyak pekerjaan membosankan [ 2 ] sehingga dapat lebih fokus ke hal yang lebih penting. Terutama bila telah lama tidak membuat lagu dan ingin kembali membuat suatu komposisi, dalam rangka mengikuti hasrat setelah suatu jeda yang panjang, membuat musik dengan kode membawa pada keputusan mepelajari Tone.js sebagai suatu langkah pertama [ 3 ]. Terdapat musisi yang membagi pengetahuannya mengenai teori musik dengan Tone.js [ 4 ] yang akan dapat sangat membantu. Tone.js merupakan suatu framework audio web untuk musik interaktif dalam penjelajah internet, yang saat ini telah mencapai rilis kelima belas dengan versi terakhirnya adalah 14.7.39 pada 29 Juli 2020 [ 5 ]. Dengan demikian tidak lagi harus memilih antara melakukan coding atau memproduksi musik, keduanya bisa sejalan [ 6 ]. Bila tidak ingin menggunakan node.js, dapat digunakan CDN Tone seperti untuk versi 14.7.77 [ 7 ] atau versi 14.8.38 [ 8 ]. Di sini akan disajikan langkah-langkah mempelajari Tone.js mengikuti suatu tulisan yang cukup baik untuk pemula [ 6 ].

Sebagai langkah awal untuk mempelajari fitur-fitur Jupyter Notebooks tersebut akan disinggung mengenai paket Python nb-js-diagrammers yang rilis terbarunya bertanggal 9 Maret 2022 untuk versi 0.0.7 [ 2 ]. Dengan paket ini empat macam diagram JavaScript, meliputi Mermaid.js , flowchart.js , wavedrom , waversurfer.js , dapat ditampilkan dalam berkas IPython Notebook dengan menggunakan cell magic.

Upaya instalasi telah dilakukan dan menemui masalah tanpa jawaban [ 3 ].

                                                                                                                                                                                                                                                                      Terdapat alternatif lain untuk menggunakan Mermaid dalam Python, seperti melaui penyisipan kode HTML dan memanggil CDN JavaScript Mermaid dan melakukan inisialisasinya dengan memanfaatkan suatu fungsi JavaScript, setTimeout() [ 4 ] atau tanpanya [ 5 ]. Alternatif lain adalah dengan merender asset dalam Jupyter Notebook yang dihasilkan oleh JavaScript menggunakan IFrame yang terembedkan dan bekerja tidak hanya untuk Mermaid akan tetapi juga untuk WaveDrom , flowchart.js , dan wavesurfer.js [ 6 ], yang sayangnya masih sulit dipahami untuk saat ini.

Dalam suatu GA solusi dinyatakan dalam bentuk individu yang memiliki sifat-sifat yang tercerminkan dalam kromosomnya [ 2 ]. Salah satu kelebihan GA adalah dapat mencegah terjadinya konvergensi terlalu dini yang mengarah pada titik optimum lokal alih-alih titik optimum global yang diinginkan dan hal ini dilakukan dengan mempertahankan keberagaman kromosom melalui operasi persilangan (crossover) dan mutasi (mutation) gen-gen pada kromosom [ 3 ]. Terdapat banyak contoh penerapan GA pada berbagai permasalahan, seperti optimasi penjadwalan perkuliahan [ 4 , 5 ] dan perencaan produksi [ 6 ]. Untuk membantu mempelajari GA telah terdapat tutorialnya [ 7 ] dan untuk menerapkannya telah terdapat pengenalan dengan contoh algoritma beserta kodenya dalam Java [ 8 ].

Terdapat penurunan hubungan ini dengan menggunakan segitiga yang menggambarkan proporsi energi kinetik dan energi diam [ 3 ] dan dua cara lain [ 4 ], yang perlu agak dikoreksi detil prosesnya. Di sini akan disinggung terlebih dahulu rumusan energi kinetiknya.

Atau secara sederhana momentum relativistik tetap menggunakan rumusan momentum akan tetapi massa yang digunakan adalah mass relativistik [ 2 ].

Terdapat peningkatan ‘massa efektif’ saat benda bergerak dengan laju mendekati laju cahaya [ 2 ]. Mengapa hal ini dapat terjadi berusaha dijelaskan dengan perubahan konsep mengenai massa dari semula merupakan pengukuran terkait dengan pengaruh gavitasi menjadi terkait dengan fenomena lokal yang disebut sebagai medan Higgs [ 3 ]. Dengan demikian saat elektron bergerak dipercepat dalam suatu senapan elektron (electron gun) perlu dilakukan koreksi massanya karena sekitar 10% laju cahaya telah tercapai [ 4 ]. Sebenarnya pengamatan telah menceritakan sebelumnya mengapa elektron yang dipercepat tidak dapat memiliki laju lebih cepat dari laju cahaya [ 5 ]. Untuk saat ini telah dapat dicapai pada LHC (large hadron collider) proton dengan laju 99.9999991% laju cahaya [ 6 ].

                                                                                                                                                                                                                                                                      length contraction

                                                                                                                                                                                                                                                                      Saat pengukur waktu bergerak mendekati kecepatan cahaya, detaknya akan melambat (atau pengukuran selang waktunya akan membesar) dan sebagai konsekuensinya jarak yang ditempuhnya akan menjadi lebih pendek [ 1 ]. Sampai dua tahun yang lalu kontraksi panjang belum pernah diukur secara langsung akan tetapi efeknya dalam bentuk besaran fisis lain telah dapat teramati [ 2 ]. Apa yang ’terlihat’ oleh muon saat begerak menuju bumi juga merupakan eksperimen mendukung adanya kontraksi panjang, yang juga tidak diukur secara langsung [ 3 ].

Fenomena ini menggambarkan bahwa sebuah jam dalam sebuah kerangka bergerak akan terlihat berjalan lebih lambat, yang sesuai dengan transformasi Lorentz [ 2 ], suatu transformasi yang dapat pula memunculkan fenomena simultanitas dan kontraksi panjang, selain dilasi waktu [ 3 ]. Dilasi waktu masih menjadi topik kajian yang menarik dewasa ini, sebagaimana telah dilaporkan pada pertengahan bulan Februari 2022 kabar mengenai mengukuran dilasi waktu pada skala terkecil yang pernah dicapai saat ini, yaitu dengan menggunakan ribuan atom ultra-dingin [ 4 ].

                                                                                                                                                                                                                                                                      time dilation

                                                                                                                                                                                                                                                                      Apa yang akan terjadi saat sebuah jam cahaya bergerak dengan cepat, mendekati laju cahaya, adalah jam akan melambat detaknya [ 1 ]. Jam cahaya yang detaknya melambat ini terlihat oleh pengamat yang bergerak relatif terhadap jam cahaya tersebut dan fenomena ini dikenal sebagai dilasi waktu yang merupakan bagian dari teori relativitas khusus [ 2 ]. Dilasi waktu atau time dilation merupakan memanjangnya rentang waktu antara dua kejadian bagi seorang pengamat dalam kerangka acuan inersial yang bergerak relatif terhadap kerangka diam, kerangka di mana dua kejadian yang diamati tersebut terjadi pada tempat yang sama [ 3 ]. Melambatnya waktu ini sebagaimana dirasakan oleh seorang pengamat dibandingkan dengan pengamat lain, bergantung pada gerak relatif mereka atau posisi terhadap medan gravitasi, yang merupakan konsekuensi dari relativitas Einstein, di mana waktu tidak bersifat absolut sebagaimana terlihatnya [ 4 ]. Suatu yang sulit diterima adalah bahwa bagaimana pada ketinggian yang berbeda dari pusat bumi, waktu akan berlalu dengan laju yang berbeda, pada tempat yang lebih tinggi posisinya waktu akan lebih cepat berubah dibanding dengan pada tempat yang lebih rendah posisinya [ 5 ].

Beberapa peristiwa yang dimaksud adalah seperti merasa gerbong kereta yang ditempati bergerak mundur hanya karena gerbong di sebelahnya bergerak maju saat berada di stasiun [ 1 ], mobil yang dikendarai tersusul oleh mobil lain yang terlihat seperti bergerak lambat [ 2 ], perahu bergerak tegak lurus sisi meyeberangi sungai tidak sampai ke titik yang dituju [ 3 ], dan bumi bergerak mengelilingi matahari dengan laju cukup besar tanpa disadari penghuninya [ 4 ].

Teknologi ini terinspirasi oleh cara kerja sistem saraf biologis, seperti pada sel otak manusia [ 2 ] atau jaringan saraf yang membentuk otak hewan [ 3 ]. Otak manusia sendiri masih menyimpan banyak misteri, di mana pemrosesan paralel yang masif mengangkat kinerja otak melebihi AI [ 4 ].

Perlu versi Python tertentu bila ingin menginstalnya menggunakan pip [ 2 ]. Selain Jupyter Notebook klasik, mungkin juga dapat dinstal JupyterLab dan Voilà bila diperlukan [ 3 ]. Untuk saat ini hanya akan diinstal Jupyter Notebook. Proses instalasi dilakukan menggunakan PowerShell 5.1.19041.1320 pada Windows 10.0.19042.

Untuk menggambarkan intensitas, umumnya perlu dirumuskan fungsinya terlebih dahulu [ 3 ]. Akan tetapi dikarenakan Gnuplot dapat menggunakan fungsi matematika dengan variabel yang dapat diatur, perumusan fungsi untuk intensitas tidak perlu dilakukan, akan tetapi cukup fungsi untuk medan listriknya saja sehingga fungsi untuk intensitas dibentuk dari fungsi untuk medan listriknya.

Untuk membantu pemahaman mengenai fasor ini, telah pula ada model mekaniknya sehingga dapat dicoba [ 3 ]. Dengan dua cara tersebut akan ditunjukkan bagaimana intensitas interferensi dua celah dapat diperoleh.

Istilah yang dimaksud di sini adalah persamaan gelombang. Istilah ini digunakan untuk persamaan yang menghubungkan laju rambat, frekuensi, dan panjang gelombang suatu gelombang [ 1 , 2 , 3 , 4 ], fungsi yang menggambarkan bentuk gelombang dan perambatannya sebagai fungsi posisi dan waktu [ 5 , 6 , 7 ], dan suatu persamaan diferensial parsial linier orde kedua [ 8 , 9 , 10 , 11 ].

                                                                                                                                                                                                                                                                      Intensitas hasil interferensi dua celah [ 1 ] dapat dijelaskan dengan penjumlahan fungsi trigonometri melalui formula Prosthaphaeresis [ 2 ] dan fasor [ 3 ]. Di sini akan disinggung beberapa pendekatan yang digunakan.

                                                                                                                                                                                                                                                                      Pada interferensi dua celah sumber cahayanya adalah kedua buah celah yang ukurannya dapat diabaikan dibandingkan dengan jarak antar kedua celah $d$. Kedua celah disinari oleh satu sumber cahaya monokromatik yang terletak di tengah-tengah kedua celah sehingga dapat dikatakan bahwa kedua celah merupakan sumber cahaya yang tidak saja monokromatik akan tetapi juga koheren.

Ini terlihat terkait dengan saat ini menggunakan theme hugo-theme-codex yang diinisialiasi Jake Wiesler [ 2 ].

Tulisan ini mencoba merekam langkah-langkah yang dilakukan untuk mencapai hal tersebut dengan menggunakan Windows PowerShell (PS) dan Git Bash, serta akses ke situs GitHub. Selain itu terdapat pula langkah tambahan untuk menambahkan submodule [ 2 ] dan menghapusnya [ 3 ], yang belum tentu diperlukan.

                                                                                                                                                                                                                                                                      python matplotlib animation

                                                                                                                                                                                                                                                                      Animasi adalah suatu metode dalam merekam gambar, model, atau bahkan boneka secara berurutan, dalam rangka menciptakan ilusi gerak, di mana hal ini dapat terjadi karena mata manusia hanya dapat mempertahankan suatu citra selama kira-kira 1/10 detik, sehingga ketika sejumlah gambar muncul berurutan secara cepat, otak memadukannya menjadi suatu gambar bergerak tunggal [ 1 ]. Grafik telah dapat menjelaskan data, animasi dapat menolong lebih jauh dengan memberikan pehamanan bagaimana keadaan berubah dengan waktu [ 2 ]. Matplotlib pada Python dapat dimanfaatkan untuk mengambarkan grafik data yang dianimasikan dengan menunda waktu penggambaran pada setiap titik data atau dengan fungsi terkait animasi yang telah disediakan [ 3 ], misalnya untuk menampilkan data bacaan potensiometer secara live [ 4 ], data multi-dimensi penduduk negara-negara yang berubah dengan tahun [ 5 ], sistem fisis seperti kurva gelombang, pendulum ganda, dan partikel-partikel dalam kotak yang saling bertumbukan [ 6 ], serta pola titik-titik air hujan yang jatuh pada suatu permukaan [ 7 ].

Sejak Windows 10 version 1607 PowerShell telah terinstal secara default [ 3 ]. Instalasi Python dengan menggunakan PowerShell akan disinggung di sini dan juga pemanfaatan pip yang telah disertakan.

Fungsi yang dimaksud merupakan sesuatu yang belum diketahui dan akan dipecahkan [ 2 ]. Metode separasi variabel merupakan salah satu metode yang sering digunakan dalam penyelesaian secara secara analitik [ 3 ] dan untuk numerik dapat digunakan beda hingga [ 4 ]. Untuk lebih mendalami PDP dapat digunakan berbagai sumber yang tersedia seperti buku [ 5 ] dan catatan kuliah [ 6 ].

Teorema ini menghubungkan antara integral suatu curl medan vektor pada suatu permukaan dengan integral garis medan vektor mengelilingi batas permukaan tersebut [ 2 ]. Dengan teorema ini dapat diperoleh persamaan-persamaan Maxwell bentuk integral dari bentuk diferensial atau sebaliknya [ 3 ].

Teorema ini menghubungkan antara fluks medan vektor yang melewati suatu permukaan tertutup dengan divergensi medan tersebut di dalam volume tertutup [ 2 ].

Metode ini mengintegrasi secara numerik persamaan diferensial biasa menggunakan langkah coba-coba pada titik tengah suatu rentang agar suku kesalahan pada orde lebih rendah saling meniadakan [ 2 ]. Anggota keluarga metode Runge-Kutta yang paling dikenal adalah RK4, metode klasik Runge-Kutta atau cukup metode Runge-Kutta [ 3 ]. Telah terdapat contoh penerapan metode ini dalam berbagai bahasa pemrograman [ 4 ]. Metode ini pun dapat dijalankan beberapa processor secara paralel dalam menyelesaikan persamaan diferensial [ 5 ].

Gelombang EM membawa energi, momentum, dan momentum angular menjauh dari partikel sumbernya dan dapat memberikan kuantitas-kuantitas tersebut pada bahan yang dilewatinya [ 2 ]. Sumber gelombang EM adalah partikel bermuatan yang dipercepat, partikel bermuatan menghasilkan medan listrik dan partikel bermuatan yang bergerak menghasilkan medan magnetik [ 3 ]. Persamaan gelombang yang muncul dari persamaan-persamaan Maxwell mendeskripsikan gelombang EM [ 4 ].

Implementasi yang dilakukan belum memuncukan nomor persamaan dan masih menggunakan MathJax versi 2.7.2 [ 2 ]. Cara Untuk memunculkan penomoran persamaan terdapat cara yang berbeda pada MathJax 3 [ 3 ] dibandingkan dengan pada versi sebelumnya.

Dapat pula dilakukan secara manual dengan selalu memperbarui berkas-berkas pada folder public dan mengaturnya pada setting GitHub Pages atau melakukan otomatisasi sepenuhnya [ 2 ]. Dapat juga dilakukan dengan bantuan Bash script untuk memperbarui, akan tetapi hasilnya agar dapat dilihat perlu dilakukan clone repo suatu blog, instal Hugo, dan isi blog dibaca secara lokal [ 3 ]. Terdapat pula cara membuat branch gh-pages yang merupakan orphan branch [ 4 ]. Di sini hanya akan dibahas bagaimana berkas-berkas yang dihasilkan Hugo dan kode dengan artikel disimpan dalam repo terpisah di GitHub [ 2 ] sebagai alternatif dari disimpan dalam repo yang sama akan tetapi pada cabang berbeda [ 1 ].

Proses instalasi Hugo dilakukan mengikuti langkah-langkah yang diberikan untuk sistem operasi Windows [ 5 ]. Saat ini digunakan sistem operasi Microsoft Windows 10 Home versi 10.0.19042 Build 19042.

Syarat batas (boundary condition, b.c.) yang merupakan kendala bagi solusi dari suatu masalah nilai batas [ 2 ]. Terdapat kajian yang menarik bahwa nomenklatur penggunakan b.c. ini tidak standar sehingga cukup membingungkan dalam bidang air tanah [ 3 ].

Untuk arus bolak-balik prinsip ini pun tetap berlaku. Dengan menggunakan tegangan pada resistor [ 1 ], induktor [ 2 ], dan kapasitor [ 3 ] dapat dibahas tegangan total pada rangkaian RLC seri yang diberik arus bolak-balik.

Secara umum sulit untuk menyelesaikan persamaan diferensial dengan syarat batas pada sepanjang tepi domain dan amat langka formula analitiknya dapat diperoleh sebagai solusi, di sini metode beda hingga berperan dengan menggantikan turunan pada persamaan diferensial dengan aproksimasi beda hingga, yang menghasilkan sejumlah besar sistem persamaan aljabar untuk dipecahkan, sebagai ganti menyelesaikan persamaan diferensial semula, yang dapat dengan mudah diselesaikan pada suatu komputer [ 2 ].

Metode Euler merupakan salah satu solusi untuk permasalahan ini, yang dapat memecahkan persamaan diferensial biasa bila diberikan suatu kondisi atau syarat awal, di mana metode ini menganalisa persamaan diferensial dengan memanfaatkan ide linearitas lokal atau pendekatan linier [ 2 ]. Metode ini diperkenalkan dalam penyelesaian persamaan diferensial biasa order pertama secara numerik karena secara umum sederhana [ 3 ] dan memiliki berbagai keterbatasan [ 4 ].

Dalam pengenalan PDB dapat diselesaikan beberapa persamaan diferensial tertentu seperti persamaan skalar order pertama, persamaan linier orde kedua, dan sistem persamaan linier [ 2 ]. Untuk persamaan diferensial dengan lebih dari satu variabel, misalnya persamaan panas, metode separasi variabel akan menghasilkan satu PDB untuk masing-masing variabel [ 3 ].

Terkait dengan hal tersebut sebuah kumparan yang dialiri arus listrik akan membangkitkan medan magnetik dan seakan-akan memiliki pula kutub utara N dan kutub selatan S, yang posisi kedua kutub ini dapat ditentukan dengan aturan tangan kanan [ 2 ].

Arus listrik yang dihasillkan oleh perubahan medan magnetik disebut sebagai arus induksi. Pernyataan bahwa arus induksi mengalir dalam arah yang sedemikian rupa melawan perubahan yang menginduksikannya (membuatnya muncul) diberikan dalam hukum Lenz [ 2 ]. Keduanya kadang bersama-sama dirujuk sebagai hukum Faraday-Lenz [ 3 ]. Terdapat berbagai konsep fisika yang terkait dengan hukum Faraday ini [ 4 ]. Fenomena induksi ini dimanfaatkan dalam trafo, generator listrik, kompor induksi, flow meter elektromagnetik untuk fluida tertentu, dan alat-alat musik listrik [ 5 ]. Dan perlu dihindari dalam rangkaian elektronik seperti pada PCB [ 6 ].

Tidak ada yang menemukan bidang miring karena obyek ini ada di dalam dan telah digunakan jauh sebelum prinsip kerjanya dipahami [ 2 ]. Keuntungan mekanik penggunaan bidang miring sama dengan rasio panjang permukaan miring terhadap tinggi bentangnya [ 3 ]. Bila tanpa kecepatan awal sebuah benda titik dapat dibahas bagaimana gerak turunnya pada bidang miring licin dan juga pada bidang miring kasar, yang dapat membuat benda berhenti atau dari awal tidak bergerak [ 4 ]. Dengan kecepatan awal yang mengarah ke atas bidang miring dapat disimulasikan sampai di mana benda akan mendaki dan kemudian diam di atas bidang miring kasar [ 5 ]. Telah terjadi diskusi apakah gerak benda mendaki bidang miring dapat digunakan sebagai analogi sistem di luar sistem fisis [ 6 ]. Beberapa skenario pendakian benda ke atas bidang miring akan disinggung di sini.

Sebelumnya suatu Dictionary merupakan koleksi tak-berurutan (unordered) nilai-nilai data, akan tetapi sejak Python 3.7 telah dimodifikasi untuk menjaga urutan penyisipan [ 2 ]. Dictionary yang untuk setiap kunci hanya memiliki satu nilai dapat diperluas menjadi bebeberapa nilai dengan menggunakan list [ 3 ], set [ 4 ], ataupun tuple [ 5 ]. Di sini akan coba disajikan untuk dua nilai yang merupakan keterangan dalam dua bahasa, yaitu bahasa Indonesia dan Inggris untuk suatu jenis item.

Massa benda $m = 4.73 \ {\rm kg}$ dan kecepatan awal benda $v_f = 0$. Ingin dicari usaha oleh gaya pada Persamaan \eqref{eqn:non-constant-force} dan kecepatan akhir benda $v_f$. Antara lantai dengan benda tidak terdapat gesekan dan lantai benar-benar mendatar sehingga gaya yang bekerja pada benda adalah hanyalah $f(x)$.

Metode ini memerlukan jumlah titik $N \ge 2$ dan $N /2 = \lfloor N/2 \rfloor$. Dengan demikian bila digunakan jumlah partisi $N$ yang dianggap pasti bernilai genap diperoleh faktor pembagi pada lebar partisi yang berbeda [ 2 ], dibandingkan dengan memilih bahwa $N = 2M$ [ 1 ].

Aturan ini merupakan salah satu dari aturan-aturan terpenting dalam teori integrasi [ 2 ]. Metode ini memerlukan jumlah titik $N \ge 2$.

Untuk tahapan sebagai berikut (belum fix karena masih dirancang): Pertama kumbang koksi diperbanyak, sambil nunggu kumbang koksi cukup banyak, tanaman stroberi diinfeksikan kutu daun. Kemudian saat kutu daun sudah banyak dihitung populasi awal, dan setelah itu ditambah kumbang koksi dan diamati perubahan populasi kutu daun.

Istilah tegangan dalam sebuah baterai mengacu pada perbedaan potensial listrik antara terminal positif dan negatif baterai [ 2 ], yang bagaimana hal ini dapat terjadi telah dijelaskan dengan model sederhana baterai [ 3 ].

Contoh rangkaian DC umumnya membahas satu baterai dengan susunan resistor seri atau paralel atau susunan seri-paralel [ 1 ] dan terdiri dari lebih satu baterai [ 2 ]. Terdapat visualisasi hanya dengan satu baterai dan satu resistor yang menggambarkan bagaimana elektron bergerak dalam rangkaian tertutup [ 3 ]. Rangkaian listrik dapat pula dieksplorasi dengan analogi menggunakan aliran air [ 4 ]. Di sini akan hanya dibahas rangkaian dengan satu baterai dan satu atau beberapa resistor.

Bersama-sama dngan pembelajaran mendalam (deep learning), pembelajaran mesin (machine learning) dan pengenalan pola (pattern recognition) merupakan topik-topik yang berkaitan dan umum digunakan dalam bidang robotika dengan kecerdasan buatan, di mana konsep pertama pengenalan pola diperkenal dalam pemrosesan citra [ 2 ]. Informasi yang tersimpan dalam suatu citra dapat digunakan untuk mendeteksi berbagai hal. Bentuk citranya pun dapat berbagai jenis. Untuk citra yang diperoleh dengan menggunakan cahaya tampak, citra yang umumnya dikenal, dapat dimanfaatkan untuk mendeteksi retak pada permukaan rel kereta [ 3 ], ukuran buah pada kanopi pohon mangga [ 4 ], dan penyakit tanaman melalui citra daunnya [ 5 ].

Selain itu terdapat pula ilustrasi yang mencerahkan mengenai kontribusi elemen arus pada suatu kawat lurus [ 3 ].

LQ dapat dimanfaatkan untuk penentuan komoditas unggul satu sektor pada tingkat kabupaten [ 2 ], beberapa sektor pada tingkat wilayah administratif yang sama [ 3 ], dan sampai tingkat nasional [ 4 ]. Nilai LQ ini kemudian dapat lebih lanjut digunakan untuk mementukan daya saing suatu kawasan dan implikasinya pada pembangunan [ 5 ]. Model gravitasi antar dua negara [ 6 ] dapat dimodifikasi, dengan mengambil acuan suatu kawasan yang sama, sehingga memberikan daya saing antar dua kawasan yang akan dibandingkan.

Dua formula eksplisit interpolasi polinomial yang umum digunakan adalah polinomial Lagrange dan Newton [ 2 ], yang bersama-sama dengan spline dimanfaatkan dalam sains data [ 3 ]. Polinomial Lagrange telah pula diimplementasikan dalam bahasa Wolfram [ 4 ].

Interpolasi dari himpunan titik-titik data didefinisikan sebagai rangkaian interpolan linier antar setiap pasang titik-titik data, yang menghasilkan kurva kontinu akan tetapi dengan turunan diskontinu [ 2 ]. Dalam bahasa pemrograman Python dengan menggunakan numpy interpolasi linier dapat dilakukan dengan hanya satu baris kode [ 3 ]. Terdapat banyak kalkulator interpolasi linier yang telah tersedia secara daring [ 4 ], yang juga dilengkapi rumusnya [ 5 ].

Dalam bidang perpajakan dan keuangan interpolasi merupakan sebagai metode statistik dengan menggunakan nilai terkait untuk memperkirakan suatu harga atau hasil sekuritas yang tidak diketahui [ 3 ].

Kadang gerak muatan-muatan bersifat amat mikroskopis dan berada dalam bahan yang disebut magnet [ 2 ]. Di sini akan dibahas gaya magnetik sebagai produk perkalian vektor dari muatan yang bergerak dengan medan magnetik yang mempengaruhinya [ 3 ].

Daya listrik dapat terdapat baik pada rangkaian arus searah maupun bolak-balik, di mana yang pertama saat ini banyak digunakan pada devais seperti monitor, laptop, smartphone, power bank, dan yang kedua pada mesin cuci, blender, kulkas, oven listrik, oven microwave [ 2 ]. Di sini akan disinggung daya pada arus searah atau DC (direct current).

Hukum Ohm dapat pula dipelajari dengan pendekatan analogi mekanika dengan benda diskrit berupa partikel ataupun benda kontinu berupa fluida [ 4 ].

Salah satu pemanfaatan JS adalah sebagai alat bantu visualisasi data [ 2 ] dan juga untuk simulasi sederhana dengan memanfaatkan elemen canvas HTML5 [ 3 ]. Untuk bugx akan dimulai program sederhana untuk visualisasi dan simulasi, sambil membangun pustakanya, bugx-vis .

Para pengembang yang melompat menggunakan bahasa pemrograman Python dari bahasa pemrograman lainnya, seperti C++ dan Java, sering dibingungkan oleh proses melewatkan argumen pada Python, di mana model data terpusat-obyek dan bagaimana model ini memperlakukan assignment adalah penyebab kebingungan ini pada tingkat fundamental [ 2 ]. Untuk menyalin suatu list sebaiknya digunakan methode .copy agar menjadi obyek yang berbeda [ 3 ], yang bila digunakan operator sama dengan = hanya akan membuat referensi antar obyek sehingga pengubahan pada obyek yang satu akan mengubah pula obyek yang lain [ 4 ]. Di sini akan dibahas membuat sebuah list dua dimensi baru, sebagai suatu matriks, yang berisi angka nol dengan ukuran yang dikehendaki. Lebih tepatnya adalah membuat suatu matriks nol baru.

Pemrograman kuadrat memiliki aplikasi pada bidang keuangan, berbagai jenis sistem komputer, statistik, produksi bahan kimia, dan algoritma untuk menyelesaikan pemrograman tak-linier yang lebih rumit [ 3 ].

Salah satu jenis pemercepat partikel adalah pemercepat partikel linier yang merupakan perluasan dari ide Wideroe mengenai sel-sel pemercepat yang memanfaatkan tegangan listrik dengan frekuensi radio yang dicocokan dengan gerak partikel [ 2 ], di mana dengan cepatnya gerak partikel sel berikutnya perlu berukuran lebih panjang dari sel sebelumnya [ 3 ]. Prinsip dasar pemercepatannya adalah menggunakan dua keping, seperti keping kapasitor dengan lubang di tengahnya, yang berbeda tegangannya sedemikian rupa sehingga dapat memproduksi medan listrik yang akan menghasilkan gaya listrik yang mempercepat gerak partikel bermuatan [ 4 ]. Selain mempercepat partikel searah dengan arah gerak semula, sistem dengan dua keping tersebut dapat pula mempercepat partikel pada arah tegak lurusnya sehingga membuat partikel berbelok ke satu arah atau ke arah lainnya bergantung pada tanda muatannya [ 5 ], dengan telah terdapat pula demonstrasinya secara daring [ 6 ].

Ada yang membaginya secara umum menjadi tiga jenis dengan dua tambahannya [ 1 ], lima jenis [ 2 ], dan enam jenis [ 3 , 4 ], dengan sebagian besarnya beririsan. Saat ini hanya akan disinggung dua jenis artikel dari irisan berbagai sumber sumber tersebut.

Gaya ini, bersama-sama dengan gaya gravitasi, gaya lemah, dan gaya kuat, merupakan empat gaya-gaya fundamental [ 2 ]. Istilah elektromagnetisme menyatukan gaya listrik dan magnetik menjadi satu kata tunggal karena kedua gaya ini disebabkan oleh suatu fenomena dasar yang sama [ 3 ]. Gaya elektromagnetik ini merupakan suatu gaya dengan rentang pengaruh tak-hingga, yang mematuhi hukum kuadrat terbalik [ 4 ].

Platform ini mengijinkan penggunanya untuk menemukan dan menerbitkan dataset, menjelajah dan membangun model dalam suatu lingkungan sains data berbasis web, bekerja dengan ilmuwan data serta perekayasa pembelajaran mesin lainnya, dan mengikuti kompetisi untuk menyelesaikan tantangan-tantangan sains data [ 2 ]. Kaggle memiliki banyak kursus singkat pada berbagai topik terkait dengan sains data, gratis, dan dapat memperoleh sertifikat setelah menyelesaikannya [ 3 ]. Mengingat bahwa kebanyakan para ilmuan data hanya paham teori dan jarang mendapatkan kesempatan untuk berlatih sebelum dipekerjakan di dunia nyata, Kaggle menjembatani hal ini dengan memberikan mereka suatu platform untuk berinteraksi dan berkompetisi dalam menyelesaikan permasalahan sebenarnya [ 4 ].

Jenis platform ini mendukung begitu banyak aktivitas keseharian kita sehingga kita menjadi bergantung padanya baik untuk kehidupan pribadi maupun profesi [ 2 ]. Istilah ini digunakan untuk mendeskripsikan sederetan layanan yang tersedia secara daring, meliputi marketplace, mesin pencari, media sosial, builder situs web daring, dan sistem pembayaran [ 3 ].

Data geospasial diolah dengan QGIS (Quantum GIS) untuk mendapatkan format tertentu [ 2 ], yang lebih lanjut dapat diolah menggunakan Vaex [ 3 ], sebagaimana sedang dikerjakan untuk sejumlah kabupaten dalam suatu daerah [ 4 ]. Penelitian ini menarik untuk dilajutkan untuk menganalisis tutupan lahan lebih jauh, misalnya menggunakan rantai Markov sebagaimana telah dikerjakan sebelumnya untuk wilayah Jawa Barat [ 5 , 6 ]. Sebuah proposal akan dibuat, terpicu dengan informasi adanya penerimaan proposal kegiatan fakultas [ 7 ] dan adanya kesesuaian dengan prioritas penelitian institusi saat ini [ 8 ]. Kasus lain [ 9 ] mungkin dapat diadaptasi untuk analisis tutupan lahan ini.

Dalam sains data secara formal masalah optimasi merupakan suatu masalah untuk mencari keadaan terbaik menurut fungsi obyektif, seperti menentukan parameter pada model random forest, posisi bidak catur, bobot jaringan saraf dalam model deep learning, atau penempatan urutan stasiun pada peta [ 2 ]. Dalam optimasi, pemrograman linier (linear programming) dan pemrograman kuadrat (quadratic programming) merupakan dua di antara sedemikian banyak sub-bidang [ 3 ]. Klasifikasi masalah optimasi dapat didasari pada keberadaan batasan, sifat variabel desain, struktur masalah, sifat persamaan-persamaan yang terlibat, nilai permisif variabel desisi, sifat deterministik variabel, separabilitas fungsi, dan jumlah fungsi obyektif [ 4 ]. Masalah optimasi masih terus dikembangkan pendekatannya, seperti adanya pendekatan menggunakan grafik yang iteraktif [ 5 ].

Lebih jauh informasi medan listrik konstan ini dapat digunakan untuk menghitung medan listrik yang disebabkan oleh dua pelat berapat muatan seragam yang berbeda baik tanda muatan ataupun besar rapat muatannya [ 2 ], dua pelat dengan rapat muatan seragam masing-masing bernilai sama akan tetapi berbeda tanda [ 3 ], dan menentukan kapasitansi kapasitor, yang sayangnya perumusan potensial listriknya masih melupakan tanda negatif, walau dapat memperoleh hasilnya [ 4 ].

Solusi diperoleh dengan mengubah versi Python yang digunakan menjadi 2.7 dan membuka lalu menyimpan berkas yang diunduh.

Hasil telusur singkat mendapatkan bahwa Teori Respons Butir (IRT, Item Response Theory) merupakah salah satu pendekatan, yang lain adalah Teori Klasik, untuk melakukan analisis butir soal [ 2 ], yang salah satu penerapannya adalah pada soal ujian akhir semester matematika kelas VIII berbentuk pilihan ganda [ 3 ]. Setelah diskusi lebih lanjut, fokus pertanyaannya adalah pada metode simulasinya, seperti Monte Carlo. Terdapat artikel pengenalan simulasi Monte Carlo yang mengulas sejarah dan prinsip simulasi ini [ 4 ] dan bidang-bidang penerapan [ 5 ].

Sistem ini dapat dibuat lebih rumit dengan menempatkan sebuah muatan titik di tengah-tengah rongga bola pejal tersebut, dengan sitemnya diberikan pada gambar berikut.

Dalam biolog simetri bola merupakan simetri yang dikenal selain bilateral dan radial, di mana hanya kelompok protozoa, Radiolaria dan Heliozoia yang menggambarkan simetri bola [ 2 ]. Istilah ini digunakan untuk mendeskripsikan geometri bintang dan planet dalam relativitas umum, untuk bumi misalnya bisa dianggap bersimetri bola maka akan diperoleh formulasi matematika yang sederhana untuk medan gravitasinya [ 3 ]. Pontesial suatu gaya sentral merupakan medan skalar dengan simetri bola dan gayanya sendiri merupakan medan vektor dengan simetri bola yang besar dan arahnya (keluar atau ke dalam saja) bergantung pada jarak dari titik origin [ 4 ]. Untuk memperoleh medan listrik dengan hukum Gauss perlu memperhatikan simetri dari distribusi muatan untuk disesuaikan dengan bentuk permukaan Gaussnya [ 5 ], yang dalam hal ini yang memiliki simetri bola.

Kelebihan metode ini adalah adanya jaminan konvergensi, akan tetapi belum dapat mendeteksi bila terdapat banyak akar [ 2 ]. Dengan dua nilai awal, nilai ketiga diperoleh sebagai titik tengah dua nilai sebelumnya yang lalu nilai terbaru ini perlu dipilih untuk menggantikan salah satu dari dua nilai sebelumnya, dengan memperhatikan bahwa akar terdapat di antara dua nilai terakhir yang disimpan, yang bersifat intuitif [ 3 ].

Hukum Coulomb dapat diturunkan dari hukum Gauss dan sebaliknya pula hukum Gauss dapat diturun dari hukum Coulomb [ 2 ]. Untuk menerapkan hukum Gauss pada distribusi muatan sehingga dapat diperoleh medan listriknya, perlu memperhatikan simetri dari distribusi muatan yang kemudian disesuaikan dengan permukaan Gauss yang digunakan [ 3 ].

                                                                                                                                                                                                                                                                      Berdasarkan kebiasaan metode-metode untuk menyelesaikan masalah dalam fisika matematika dapat dibagi menjadi dua kelas, metode analitik (analytical methods) dan metode hampiran (aproximate methods) [ 1 ]. Dalam matematika beberapa masalah dapat dipecahkan secara analitik dan numerik, dengan metoda analitik lebih disukai karena lebih cepat dan solusinya eksak [ 2 ]. Solusi eksak dalam fisika digunakan untuk solusi yang menangkap keseluruhan aspek fisika dan matematika suatu masalah [ 3 ], karena tidak menggunakan aproksimasi [ 4 ] dan merupakan representasi simbolik [ 5 ], yang bila cukup dengan jumlah data berhingga akan menjadi bentuk tertutup atau closed form [ 6 ]. Dalam komputasi matematika metode iteratif (iterative method) merupakan prosedur matematika yang menggunakan nilai awal untuk menghasilkan rangkaian hampiran solusi yang lebih baik dengan kriteria penghentian tertentu, di mana metode ini berlawanan dengan metode langsung (direct method) yang menyelesaikan masalah dengan sejumlah berhingga rangkaian operasi [ 7 ].

                                                                                                                                                                                                                                                                      quadratic formula

                                                                                                                                                                                                                                                                      Persamaan kuadrat atau disebut juga persamaan dengan derajat dua memiliki bentuk $ax^2 + bx + c = 0$ dengan $a$, $b$, $c$ diketahui, $a \ne 0$, dan $x$ merupakan nilai yang ingin dicari [ 1 ]. Nilai $x$ dapat diperoleh dengan melengkapi bentuk kuadrat dari persamaan kuadrat [ 2 ], sehingga memberikan formula kuadrat [ 3 ].

                                                                                                                                                                                                                                                                      equation and formula

                                                                                                                                                                                                                                                                      Persamaan kuadrat berbentuk

                                                                                                                                                                                                                                                                      electric flux

                                                                                                                                                                                                                                                                      Fluks listrik merupakan salah satu sifat medan listrik yang dapat dibayangkan sebagai jumlah garis medan listrik yang berpotongan dengan suatu luas yang diberikan [ 1 ], di mana kerapatan garis-garis ini terkait dengan kekuatan medan listrik [ 2 ]. Konsep fluks ini selalu didefinisikan berdasarkan suatu permukaan dan sebuah medan, yang dalam hal ini adalah medan listrik [ 3 ]. Terdapat ilustrasi peran medan, luas permukaan, dan sudut antar keduanya yang bersifat interaktif [ 4 ].

                                                                                                                                                                                                                                                                      rectangular rule

                                                                                                                                                                                                                                                                      Istilah aturan persegi panjang atau rectangular rule umumnya mengacu pada pendekatan titik tengah atau midpoint, baik secara eksplisit dinyatakan [ 1 ] ataupun secara implisit dalam penjelasannya dengan menggunakan simbol lain [ 2 ]. Penggunaan partisi untuk mendekati luas di bawah kurva dapat pula menggunakan pendekatan ujung-kiri (left-endpoint) dan ujung-kanan (right-endpoint) [ 3 ], serta ukuran partisi yang tidak perlu sama [ 4 ]. Di sini hanya akan dibahas pendekatan dengan ujung-kir, ujung-kanan, dan titik tengah.

                                                                                                                                                                                                                                                                      gaussian surface

                                                                                                                                                                                                                                                                      Saat membicarakan hukum Gauss, terdapat konsep permukaan Gauss yang merupakan suatu permukaan khayal [ 1 ], suatu konstruksi matematika yang dapat berbentuk permukaan berbentuk apa saja asalkan tertutup, yang dalam implementasinya untuk meghitung fluks dengan permukaan, akan lebih mudah diselesaikan bila bentuk permukaan yang dipilih memiliki simetri tertentu [ 2 ]. Permukaan tertutup bukan merupakan permukaan Gauss walaupun permukaan dengan luas tak-hingga dapat merupakan pendekatan permukaan Gauss [ 3 ]. Terdapat pemahaman bahwa sudut antara suatu permukaan Gauss dengan medan listirk yang menembusnya perlu selalu tetap [ 4 ], yang tepat bila tujuan utama hukum ini adalah untuk memperoleh medan listrik dari distribusi muatan yang terlingkupi permukaan tertutup [ 5 ]. Akan tetapi bukan hanya itu pemanfaatan dari hukum Gauss sebenarnya. Terdapat pula informasi bahwa hukum Gauss dapat diterapkan untuk distribusi medan listrik oleh muatan cincin [ 6 ], yang seharusnya memerlukan syarat simetri untuk analisis Gauss agar produktif, kecuali bila merupakan penerapan solusi analisis beda hingga [ 7 ].

                                                                                                                                                                                                                                                                      programming paradigm

                                                                                                                                                                                                                                                                      Istilah paradigma pemrograman terkait dengan suatu gaya dalam memrogram dan tidak terkait dengan suatu bahasa pemrograman tertentu [ 1 ]. Suatu bahasa pemrograman dapat diklasifikasikan dalam lebih dari satu paradima [ 2 ], yang sebagai contohnya adalah JavaScript yang mengijinkan untuk membuat kode dalam berbagai paradima berbeda atau mengombinasikannya dalam suatu pendekatan multi-paradigma [ 3 ]. Saat berbicara mengenai empat paradigma utama pemrograman, terdapat imperatif, logikal, fungsional, dan berorientasi-obyek [ 4 ] ataupun prosedural, berorientasi-obyek, fungsional, dan logikal [ 5 ], di mana pada pembagian lain paradigma prosedural dan berorientasi-obyek merupakan bagian dari paradigma imperatif, sedangkan paradigma logikal dan fungsional merupakan bagian dari paradigma deklaratif [ 6 ]. Selain itu terdapat juga pembagian yang lebih menerus yang sampai menggunakan istilah paradigma yang lebih deklaratif dan paradigma yang lebih imperatif dan terdapat satu kelompok paradigma di antara keduanya [ 2 ]. Di sini akan dibahas dua kelompok paradigma, yaitu yang termasuk imperatif dan deklaratif serta beberapa contoh yang termasuk di dalamnya.

                                                                                                                                                                                                                                                                      root

                                                                                                                                                                                                                                                                      Dalam matematika akar merupakan suatu solusi dari suatu persamaan, yang biasanya dinyatakan sebagai angka atau formula aljabar [ 1 ]. Solusi yang dimaksud adalah membuat suatu persamaan menjadi bernilai nol sehingga sering dikatakan sebagai pembuat nol [ 2 ]. Namun agar diperhatikan bahwa terdapat penggunaan kata akar sebagai cara ringkas untuk menyatakan akar kuadrat [ 3 ]. Terdapat berbagai algoritma untuk mencari akar suatu persamaan dengan salah satu penggolongannya adalah metode kurung, interpolasi, metode iteratif, dan kombinasi berbagai metode [ 4 ]. ROOT suatu framework analisis data sumber-terbuka, ditulis utamanya dalam C++, yang digunakan dalam fisika energi tinggi dan lainnya menyediakan kelas pencarian akar satu dimensi [ 5 ], sebagaimana SciPy suatu piranti lunak sumber-terbuka, berbasiskan Python, untuk matematika, sains, dan rekayasa yang menyediakan setidaknya delapan algoritma untuk mencari akar suatu fungsi skalar [ 6 ]. Atau dapat pula suatu program dituliskan dalam Python tanpa perlu impor modul apapun [ 7 ].

                                                                                                                                                                                                                                                                      flowchart

                                                                                                                                                                                                                                                                      Diagram alir (en: flowchart) merupakan jenis diagram yang merepresentasikan suatu algoritma, aliran kerja, atau proses, menggunakan berbagai bentuk kotak bermakna tertentu sebagai langkah-langkah dan panah yang menghubungkan kotak-kotak tersebut sebagai arah langkah-langkah [ 1 ]. Dapat dikatakan bahwa diagram alir merupakan suatu representasi grafis dari suatu algoritma dengan berbagai keuntungan dan kerugiannya [ 2 ]. Dalam mengajarkannya dapat dilakukan dengan per tahap, seperti mulai dulu dengan tugas yang sudah akrab, perluas pengetahuan dengan melibatkan pengambilan keputusan, dan akhir dengan terapkan pada pengenalan pola ke instruksi pengulangan [ 3 ]. Setidaknya terdapat enam bentuk kotak standar yang digunakan dan berbagai kotak lainnya [ 4 ], yang kadang dinamai berbeda. Untuk membuatnya dapat digunakan aplikasi daring seperti Lucidchart [ 5 ] atau luring seperti Visio, yang juga sudah ada versi webnya [ 6 ], atau alternatif-alternatif lainnya yang lintas sistem operasi atau hanya menggunakan penjelajah internet [ 7 ].

                                                                                                                                                                                                                                                                      pseudocode

                                                                                                                                                                                                                                                                      Secara harfiah pseudocode berarti kode palsu, yang merupakan cara informal dan dibuat-buat dalam penulisan program dengan menyampaikan urutan tindakan dan instruksi (algoritma) dalam bentuk yang mudah dipahami manusia [ 1 ]. Atau dapat dikatakan bahwa pseudocode merupakan suatu metodologi yang mengijinkan programer untuk menampilkan implementasi suatu algoritma [ 2 ]. Dalam pseudocode detil yang penting agar mesin (komputer) dapat memahami algoritma, seperti deklarasi variabel dan kode khusus bahasa, diabaikan atau tidak digunakan [ 3 ]. Mencari luas lapangan sepak bola, menentukan bilangan genap atau ganjil, menghitung mundur, menghitung luas segitiga, dan menghitung luas lingkaran dapat menjadi contoh kasus untuk pseudocode [ 4 ].

                                                                                                                                                                                                                                                                      very short intro to github

                                                                                                                                                                                                                                                                      GitGub menyatakan bahwa dirinya merupakan tempat di mana para pengembang seluruh dunia membangun piranti lunak bersama-sama, yang saat ini melibatkan 73+ juta pengembang, 4+ juta organisasi, 84% perusahan dalam daftar Fortune 100 [ 1 ]. Terkait dengan belajar programing, terdapat pendapat bahwa GitHub bukan tempat para pemula untuk mulai memrogram dikarenakan pemula seharusnya tidak dikuatirkan dulu dengan sintaks dan perintah yang kompleks, tapi lebih mencoba mengerti bagaimana membuat kode, logika dalam menghadapi problem membuat kode, atau mengerti kode orang lain [ 2 ]. Walaupun demikian ada yang mengibaratkan bahwa bila GitHub merupakan tempat yang baik untuk belajar membuat kode, maka medan perang merupakan tempat yang baik untuk belajar menggunakan senjata api [ 3 ]. Salah satu miskonsepsi utama tentang GitHub adalah anggapan bahwa itu adalah suatu alat pengembang, sebagai bagian dari koding seperti bahasa pemrograman dan compiler, sementara yang lebih tepat bahwa GitHub adalah suatu jejaring sosial di mana penggunanya menyimpan program dan kode proyek, dan membagikannya [ 4 ]. Git sendiri adalah piranti lunak pengendali versi yang bersifat bebas dan sumber terbuka, dibuat oleh Linus Torvalds pada tahun 2005, yang semula dikembangkan untuk bekerja pada kernel Linux dengan beberapa pengembang [ 5 ]. Github merupakan platform hosting pertama untuk Git yang diluncurkan tahun 2008, kemudian diikuti dengan Gitlab yang merupakan platform hosting repositori berbasis git yang dilucurkan tahun 2011, dan terdapat pula BitBucket sebagai layanan hosting kode sumber daring lainnya yang diluncurkan pada tahun 2008 dan mulai menggunakan git sejak Oktober 2011 [ 6 ].

                                                                                                                                                                                                                                                                      algorithm

                                                                                                                                                                                                                                                                      Dalam arti yang luas algoritma merupakan suatu prosedur langkah-per-langkah untuk memecahkan masalah atau mencapai suatu tujuan [ 1 ]. Contoh yang umum untuk suatu algoritma adalah suatu resep, yang berisikan instruksi khusus untuk menyiapkan hidangan atau makanan [ 2 ] atau untuk mencapai sekolah dari rumah, menyiapkan roti sandwich keju bakar, dan mencari barang yang diingkan di kelontong [ 3 ]. Dalam istilah komputer, suatu algoritma merupakan seperangkat instruksi yang telah terdefinisi dengan baik untuk menyelesaikan suatu masalah tertentu, yang membutuhkan beberapa masukan dan menghasilkan suatu keluaran [ 4 ]. Algoritma penting bagi komputer dalam memproses data, di mana banyak program komputer berisikan algoritma yang merinci instruksi khusus apa yang harus dilakukan oleh sebuah komputer [ 5 ].

                                                                                                                                                                                                                                                                      problem solving

                                                                                                                                                                                                                                                                      Pemecahan masalah (en: problem solving), yang merupakan istilah umum, dapat membingungkan, terlebih dengan tersedianya berbagai alat bantu, bahkan sampai orang-orang dalam perusahaan yang sama menggunakan pendekatan dan terminologi yang berbeda, sehingga hal ini membuat pemecahan masalah menjadi problematik [ 1 ]. Terdapat panduan 14 langkah kritis pertama untuk menyelesaikan suatu masalah [ 2 ], 8 langkah untuk menyelesaikan masalah [ 3 ], 5 langkah untuk membuat proses pemecahan masalah lebih mudah [ 4 ], 4 langkah dasar proses memecahkan masalah yang dilengkapi dengan metodologinya [ 5 ], 3 langkah dasar pemecahan masalah [ 1 ]. Untuk pemecahan masalah komputasi terdapat lima langkah yang sudah lebih spesifik dengan melibatkan model matematika dan penggunaan komputer [ 6 ]. Walaupun komputer dapat digunakan untuk membantu memecahkan masalah, akan sebelum suatu masalah tersebut ditangani, ia perlu terlebih dahulu dimengerti, yang hal ini dapat dibantu dengan berpikir komputasi (en: computational thinking), yang mengijinkan kita untuk mengambil suatu masalah rumit, memahaminya, dan mengembangkan solusi yang mungkin, dengan solusi dapat dinyatakan dalam bentuk yang dimengerti komputer, manusia atau keduanya [ 7 ]. Salah satu versi langkah-langkah berpikir komputasi terdiri dari tiga langkah, yang meliputi spesifikasi masalah (abstraksi, dekomposisi, pengenalan pola), ekspresi algoritma (perancangan algoritma), dan implementasi solusi & evaluasi (generalisasi) [ 8 ].

                                                                                                                                                                                                                                                                      discrete charge dist 3d

                                                                                                                                                                                                                                                                      Dalam pembelajaran perhitungan medan listrik oleh sejumlah titik muatan dalam 3d, salah satu problemnya adalah sistem berbentuk sejumlah muatan yang terletak pada titik-titik sudut sebuah kubus [ 1 ]. Visualiasi medan listrik oleh beberapa muatan titik dalam 3d, juga permukaan ekipotensialnya, dapat digambarkan menggunakan software Maple 10 [ 2 ]. Dalam aplikasinya medan listrik dalam tiga dimensi menjadi penting sehingga perlu dihitung dan diukur di substation bertegangan tinggi [ 3 ] dan dimodelkan untuk membantu analisis pada sistem peringatan petir [ 4 ]. Untuk saat ini tiga muatan titik pada sudut-sudut suatu kotak dan kontribusinya pada suatu titik amat akan dibahas sebagai ilustrasi superposisi medan listrik [ 5 ], yang dalam hal ini bersumber dari tiga muatan titik. Sistem ini dapat diperluas menjadi bersumber dari $N$ muatan titik.

                                                                                                                                                                                                                                                                      discrete charge dist 2d

Suatu bahan berjenis konduktor mengijinkan muatan bebas untuk bergerak di dalamnya [ 2 ] dan telah ditelaah bagaimana distribusi muatan diskrit tersebut pada berbagai bentuk konduktor dua-dimensi yang bersimetri, meliputi elips, hypotrochoid, dan bermacam poligon [ 3 ]. Di sini untuk sementara akan dibahas sistem dua dimensi untuk muatan diskrit yang terikat, tidak mudah bergerak, dan medan listrik yang dihasilkannya pada sebuah titik amat tertentu.

                                                                                                                                                                                                                                                                      discrete charge dist 1d

                                                                                                                                                                                                                                                                      Sistem kristal paling sederhana yang dapat digunakan untuk menghitung sifat fonon adalah sebuah rantai atom-atom yang berjarak sama yang geraknya dibatasi pada satu-dimensi [ 1 ]. Bila atom-atom tersebut kehilangan atau ketambahan elektron akan menjadi ion, sehingga terdapat kristas ion satu-dimensi, yang misalnya ingin dihitung energi kohesinya [ 2 ]. Salah satu sistem atom 1d yang ada adalah carbyne, suatu rantai atom-atom karbon yang berikatan ganda atau alternasi ikatan tunggal dan triple, yang sayangnya belum cukup stabil [ 3 ] dan telah terdapat perhitungannya menggunakan prinsip pertama [ 4 ]. Dalam hal kekuatan tarik spesifik carbyn menggungguli grafena, nanotube karbon, dan intan [ 5 ]. Kembali ke sistem ion 1d, walaupun hanya merupakan sistem kristal hipotetical [ 6 ], akan tetapi tetap menarik untuk dipelajari dan bermanfaat. Salah satunya adalah saat menyederhanakan analisis dari kisi atom 3d dengan memodelkannya menjadi kisi 1d atau rantai linier, misalnya dalam mempelajari fonon [ 7 ].

                                                                                                                                                                                                                                                                      discrete charge distribution

                                                                                                                                                                                                                                                                      Konsep mengenai distribusi diskrit dan kontinu muatan kadang masih membingungkan terutama dalam penerapannya untuk sistem yang sama akan tetapi dengan berbeda cara pandang, dan pendekatannya dengan fungsi kontinu untuk distribusi diskrit [ 1 ]. Terdapat buku teks dengan bab Distribusi Diskrit Muatan yang di dalamnya tidak menceritakan distribusi muatan melainkan hanya satu, dua, atau sejumlah muatan yang dipandang sebagai titik-titik muatan yang terpisah [ 2 ], sebagai pembeda dengan bab berikutnya Distribusi Muatan kontinu yang dalam menghitung medan listriknya perlu menggunakan integral [ 3 ]. Dalam aplikasinya telah ditelaah energetik dan kestabilan distribusi diskrit muatan pada permukaan bola [ 4 ] dan untuk studi mengenai bahan pada skala nano perlu hati-hati dalam membuat model terkait muatan titik diskrit dalam bahan dielektrik [ 5 ]. Terdapat pula studi mengenai proses pemberian muatan pada partikel nano yang memperlihatkan situs-situs muatan diskrit [ 6 ]. Di sini yang dimaksud dengan distribusi diskrit muatan adalah terdapatnya fungsi menjelaskan posisi titik-titik muatan.

                                                                                                                                                                                                                                                                      Medan listrik oleh banyak muatan titik pada suatu titik amat merupakan penjumlahan secara vektor medan listrik oleh setiap muatan di titik tersebut [ 1 ], yang untuk sistem dua muatan titik amat dapat berada segaris dengan kedua muatan ataupun di luar garis yang menghubungkan kedua muatan [ 2 ]. Dengan menggunakan simulasi interaktif PhET total medan listrik pada suatu titik amat akibat banyak muatan dapat dengan mudah diilustrasikan [ 3 ].

                                                                                                                                                                                                                                                                      electric field and source

                                                                                                                                                                                                                                                                      Konsep medan listrik digunakan untuk melakukan visualisasi bagaimana sebuah muatan atau kumpulan muatan mempengaruhi daerah di sekitarnya, yang merupakan suatu analogi dengan $g$ yang walau disebut sebagai percepatan gravitasi, akan tetapi sebenarnya merupakan medan gravitasi [ 1 ]. Sumber medan listrik dapat berupa satu atau beberapa muatan titik [ 2 ], distribusi kontinu muatan [ 3 ], ataupun medan magnetik yang berubah terhadap waktu [ 4 ]. Terdapat diskusi menarik mengapa sumber yang terakhir yang bersifat dinamis tidak dibedakan, misalnya dengan notasi yang berbeda, terhadap sumber yang bersifat statis [ 5 ]. Lebih dalam lagi sifat, asal, dan perambatan medan listrik, telah dikaji dan menghasilkan wawasan baru untuk fisika fundamental mengenai hal ini yang didasarkan atas kehadiran string yang bervibrasi dalam ruang dan proses eksitasi-dirinya [ 6 ]. Di sini hanya akan dibahas medan listrik yang disebabkan oleh satu muatan titik, beberapa muatan titik, dan distribusi kontinu muatan.

                                                                                                                                                                                                                                                                      elec force field potential

Garis-garis medan listrik yang disebabkan oleh sebuah muatan listrik merupakan lintasan yang akan dilalui oleh muatan uji yang semula diam, saat diletakkan dalam pengaruh medan listrik tersebut [ 2 ]. Agar muatan uji berubah keadaan geraknya dari diam menjadi bergerak mengikuti garis-garis medan listrik memerlukan gaya, gaya ini yang disebut sebagai gaya elektrostatik atau gaya listrik. Potensi suatu medan listrik untuk membuat muatan uji bergerak menempuh garis-garis gaya listrik disebut sebagai potensial listrik [ 3 ]. Hubungan gaya gaya elektrostatik antar muatan sumber dan muatan uji dengan medan listrik yang disebabkan muatan sumber, dan hubungan antara medan listrik dengan potensial listrik akan disajikan secara ringkas di ini.

Hal ini akan membuat bentuk-bentuk seperti sektor lingkaran [ 4 ] dan segmen anulus [ 5 ] tidak dapat digunakan sebagai bentuk muatan permukaan untuk dihitung medan listrik yang disebabkannya. Dengan menggunakan elemen luas lingkaran, sebagai cara terakhir dari tiga cara mengitung luas lingkaran [ 6 ], hasil yang lebih umum dapat diperoleh.

Di sepanjang sumbu cakram medan listrik merupakan fungsi dari jarak terhadap pusat cakram [ 3 ]. Ketimbang langsung membahas cakram, formulasi yang tersedia dapat diperluas menjadi bentuk anulus, suatu cakram dengan lubang berupa lingkaran tepat di tengah-tengahnya [ 4 ].

Sebagai sumbu cincin dapat dipilih sumbu $z$ [ 1 ] atau sumbu $x$ [ 2 ]. Telah terdapat video penurunannya [ 3 ] dan juga perhitungan numeriknya menggunakan VPython [ 4 ]. Dengan mengananalogikan muatan listrik dengan massa, terdapat titik maksimum nilai medan di sepanjang sumbu cincin [ 5 ].

                                                                                                                                                                                                                                                                      lin chrg e field rect loop

Bagaimana bila loop segiempat ini terbentuk dari muatan garis? Apakah menarik untuk dibahas? Setidaknya bahasan ini dapat digunakan untuk melatih pemanfaatan rumusan medan listrik yang disebabkan oleh muatan garis dengan panjang berhingga.

                                                                                                                                                                                                                                                                      line charge e field beyond

Selain itu terdapat pula posisi lain, yaitu pada jarak tertentuk dari ujung kawat dan menerus dari panjang kawat [ 4 ], yang penurunannya agak sedikit berbeda. Kedua kelompok kasus ini dapat diperoleh bila pada awal perumusannya medan listrik dihitung pada posisi jauh di luar sisi panjang kawat, yang dapat memberikan gambaran lebih umum, akan tetapi sering diabaikan atau dibahas dengan tidak lengkap pada banyak buku teks [ 5 ].

                                                                                                                                                                                                                                                                      line charge electric field

Medan listrik di sekitar kawat lurus dapat dihitung pada posisi tengah-tengah panjang kawat sehingga dapat memanfaatkan simetri untuk memudahkan perhitungan [ 3 ] atau menghitungnya pada sembarang posisi di sekitar kawat lurus sehingga memberikan hasil yang lebih umum [ 4 ]. Salah satu kasus yang menarik adalah bila panjang kawat dapat dianggap tak-hingga atau jauh lebih besar dari jarak titik yang ingin diobservasi terhadap kawat [ 5 ]. Terdapat pula kasus di mana medan listrik dihitung pada jarak tertentu dari salah satu ujung kawat lurus, yang kadang dapat cukup membingungkan [ 6 ].

Akan tetapi perlu diingat bahwa karena muatan terkuantisasi, tidak terdapat distribusi muatan yang benar-benar kontinu [ 2 ]. Seperti halnya rapat massa, rapat muatan dapat bergantung posisi dan dalam teori elektromagnetik klasik rapat muatan diidealisasi sebagai suatu fungsi skalar kontinu dari posisi sebagaimana fluida [ 3 ]. Untuk distribusi muatan kontinu terdapat rapat muatan garis, rapat muatan luas, dan rapat muatan volume [ 4 ]. Dengan menggunakan ketiga rapat muatan ini dan bersama-sama dengan susunan muatan titik, dapat dibuat generalisasi hukum gaya Coulomb untuk keempat macam distribusi muatan (volume, permukaan, linier, dan titik) menjadi penjumlahan dari tiga integral dan satu somasi [ 5 ]. Terdapat pula keadaan khusus saat setiap muatan yang melingkupi suatu ruang dengan dimensi jauh lebih kecil dari jaraknya terhadap titik pengamatan dapat dianggap sebagai suatu titik muatan [ 6 ].

Nugraha. Kegiatan tersebut belum terkait dengan kegiatan 1st ITB Graduate School Conference (i-GSC) yang diselenggarakan oleh SPs dan LPPM ITB [ 2 ], yang dilaksanakan secara daring [ 3 ] untuk mahasiswa pascasarjana.

Salah satu pendekatan untuk memahami konsep pontensial listrik adalah dengan menggunakan analogi gravitasi [ 2 ]. Potensial listik didefinisikan sebagai jumlah kerja yang diperlukan untuk memindahkan satu satuan muatan dari suatu titik referensi ke suatu titik tertentu dalam medan listrik, yang lebih tepatnya adalah energi per satuan muatan untuk suatu muatan uji yang sedemikian kecil sehingga tidak mengganggu medan listrik yang sedang diamati [ 3 ]. Lazimnya titik referensi yang digunakan adalah bumi, akan tetapi setiap titik di luar pengaruh medan listrik muatan sumber dapat digunakan [ 4 ]. Potensial listrik oleh satu muatan titik, kadang secara implisit, mengambil titik referensi pada jarak jauh tak-hingga sebagai potensial listrik bernilai nol [ 5 ].

Dalam matakuliah ini mahasiswa program doktor dibimbing agar dapat menghasilkan publikasi internasional pada jurnal internasional terindeks Scopus yang secara teknis dijalankan langsung oleh tim promotor S3 masing-masing mahasiswa di bawah koordinasi Ketua Program Studi S3, sehingga mahasiswa dapat melakukan penelitian berkualitas yang hasilnya dapat dipublikasikan, dengan kegiatan keseluruhan berlangsung selama 16 minggu pertemuan yang disediakan untuk mencapai satu luaran [ 2 ]. Rujukan yang terkait dan mendukung topik penelitian dapat digunakan.

Konsep medan listrik muncul dalam upaya untuk menjelaskan gaya-gaya yang dapat berinteraksi pada jarak jauh, di mana semua benda bermuatan menciptakan medan listrik yang meluas keluar dari muatan ke ruang di sekelilingnya [ 2 ]. Dengan konsep ini hukum Coulomb yang menjelaskan gaya antara dua muatan yang terpisahkan jarak dapat direformulasi dalam dua langkah terpisah [ 3 ]. Sebagai suatu besaran vektor medan listrik dapat divisualisasikan dengan panah mengarah ke atau berasal dari muatan-muatan, yaitu masuk secara radial ke muatan negatif dan keluar secara radial dari muatan positif [ 4 ]. Benda bermuatan penyebab medan listrik dapat berupa titik muatan, sejumlah titik muatan, silinder bermuatan, bolah bermuatan, dan pelat paralel bermuatan [ 5 ]. Medan listrik ini berperan penting dalam banyak bidang fisika dan dieksploitasi secara praktis dalam teknologi kelistrikan [ 6 ].

Gaya elektrostatik termasuk di dalam gaya elektromagnetik [ 9 ], dengan gaya elektromagnetik bersama-sama dengan gaya gravitasi, gaya nuklir kuat, dan gaya nuklir lemah merupakan empat gaya fundamental yang membentuk kompleksitas alam semesta di sekitar kita [ 10 ].

Dengan hanya berbekal aplikasi peyunting teks polos dan penjelajah internet pembuatan suatu halaman web, yang bergaya dan interaktif, serta dapat disisipkan berbagai jenis media, dapat dibuat secara lokal.

Untuk mempelajari artificial neural network (ANN), atau lebih dikenal hanya sebagai neural network (NN), dewasa ini dapat dilakukan dengan langsung mencobanya secara daring, mulai dari yang memiliki antarmuka sederhana dan hanya menampilkan arsitektur jaringannya [ 3 ], dilengkapi dengan hyperplane [ 4 ], sampai dilengkapi visualisasi menarik [ 5 ] sehingga dapat dikembangkan menjadi semacam kalkulator NN dalam merancang detektor trojan [ 6 ]. Selain itu terdapat pula platform yang lebih terintegrasi dan dapat diterapkan ke bisnis [ 7 , 8 ].

                                                                                                                                                                                                                                                                      numerical integration

                                                                                                                                                                                                                                                                      Terdapat banyak fungsi yang antiderivatifnya tidak dapat atau tidak secara mudah diekspresikan dalam bentuk tertutup, atau dengan kata lain dalam bentuk fungsi yang diketahui, sehingga ketimbang mengerjakan integral dari fungsi-fungsi tersebut secara langsung, lebih baik mencari jalan lain dengan berbagai teknis integrasi numerik untuk mencari nilai aproksimasi integralnya [ 1 ]. Dalam matematika suatu jenis aproksimasi dari suatu integral menggunakan jumlah berhingga dikenal sebagai jumlah Riemann, yang penerapan umumnya adalah untuk menghampiri luasan suatu fungsi atau garis pada grafik, dan juga panjang kurva serta hampiran lainnya, di mana jumlah tersebut dihitung dengan membuat partisi daerah menggunakan bentuk-bentuk tertentu, seperti kotak, trapesium, parabola, atau kubik [ 2 ]. Pendekatan menggunakan titik kiri kotak (LRAM), titik tengah kotak (MRAM), dan titik kanan kotak (RRAM) termasuk ke dalam metode pendekatan kotak atau rectangular approximation method [ 3 ], yang merupakan contoh formulasi yang dapat bervariasi dari suatu pendekatan. Untuk midpoint rule atau aturan titik tengah, nama lain dari midpoint rectangular approximation method, terdapat contoh kode dalam R [ 4 ]. Kemudian, selain dengan menggunakan partisi, integrasi numerik dapat pula dilakukan dengan menggunakan bilancan acak, seperti pada integrasi Monte Carlo [ 5 ].

                                                                                                                                                                                                                                                                      py iterable for list range

                                                                                                                                                                                                                                                                      Dalam Python loop dengan for digunakan untuk proses berkelanjutan yang berurutan (sequential traversal) seperti pengulangan pada suatu iterable seperti string, tuple, list, array dan lainnya, yang termasuk dalam kategori iterasi terdefinisi [ 1 ]. Terdapat perbedaan antara range dan list, yang sejak Python 3.x range tidak lagi memproduksi list sehingga elemen-elemennya tidak lagi memerlukan memori untuk menyimpannya, melainkan hanya dibuat on the fly saat iterasi dilakukan, sehingga proses iterasinya menjadi lebih cepat [ 2 ].

                                                                                                                                                                                                                                                                      py simple sort

Algoritma sederhana ini bekerja buruk dalam penggunaan sebenarnya dan pemanfaatan utama algoritma ini adalah untuk alat edukasi [ 3 ]. Dalam Python telah terdapat metode dan fungsi bawaaan untuk mengurutkan larik berjenis list, yaitu sort() [ 4 ] dan sorted() [ 5 ].

                                                                                                                                                                                                                                                                      py array mul add num

                                                                                                                                                                                                                                                                      Array merupakan struktur data yang terdiri dari kumpulan elemen, berupa nilai atau variabel, yang dirujuk dengan setidaknya satu indeks atau key, di mana dalam implementasinya yang bergantung pada bahasa pemrograman jenis array ini dapat beririsan dengan jenis data lainnya yang menyimpan agregat nilai seperti list dan string [ 1 ]. Larik merupakan terjemahan array dalam bahasa Indonesia [ 2 ]. Dalam Python terdapat perbedaan antara array dan list [ 3 ], yang saat mengaksesnya dapat melalui iterasi [ 4 ] ataupun terlihat tidak [ 5 ]. Cara yang terakhir ini terlihat lebih elegan akan tetapi memerlukan pemahaman akan adanya iterasi yang berlangsung secara tersirat. Untuk membantu pemahaman kode lengkap yang disajikan dapat dicoba langsung pada kompiler daring seperti OneCompiler [ 6 ].

Pengaruh dari muatan dikarakterisasi dalam istilah gaya antar muatan, dalam hukum Coulomb, dan medan magnetik dan tegangan yang dihasilkannya [ 2 ]. Muatan listrik bersifat kekal, yang artiniya total muatan suatu sistem terisolasi, yaitu selisih muatan positif dan negatif, tidak berubah [ 3 ]. Saat dua buah bahan isolator saling bergesekan masing-masing dapat menjadi bermuatan berbeda karena elektron terhapus dari satu bahan dan pindah ke bahan lainnya, sehingga bahan yang kehilangan disebut menjadi bermuatan positif dan bahan yang ketambahan disebut menjadi bermuatan negatif [ 4 ]. Satuan SI muatan listrik adalah coulomb atau $\rm C$, dari nama fisikawan Perancis Charles Augustine de Coulomb (1736–1806) [ 5 ].

                                                                                                                                                                                                                                                                      Mengukur sudut dalam fisika tidaklah selalu menggunakan referensi yang sama seperti dalam matematika, di mana telah terdapat istilah sudut rujukan $\theta$, yang diukur terhadap sumbu $x$ dan selalu bernilai antara $0$ dan $90$, yang merupakan sudut terkecil (acute angle) yang dibentuk oleh sisi akhir (terminal side) dan sumbu $x$ [ 1 ]. Untuk benda yang meluncur menuruni bidang miring, sudut kemiringan bidang diukur terhadap arah horisontal dan dipilih sudut terkecilnya baik untuk bidang miring licin [ 2 ] maupun dengan gesekan [ 3 ], yang hubungan sudut ini dengan sudut untuk menguraikan gaya-gaya yang bekerja pada benda kadang masih membingungkan [ 4 ]. Untuk pendulum sederhana sudut ayunan diukur terhadap arah vertikal baik untuk gerak dengan sudut simpangan kecil [ 5 ] ataupun besar [ 6 ], yang memudahkan perumusan aproksimasinya [ 7 ]. Benda yang ditarik sepanjang lantai mendatar sudut gaya diukur terhadap arah mendatar baik untuk gaya tarik [ 8 ] ataupun gaya dorong [ 9 ]. Acuan arah mendatar ini menjadi arah gerak benda bila lintasannya telah pasti seperti pada rel [ 10 ] atau arahnya merupakan informasi yang diketahui [ 11 ]. Pada gelombang sudut datang [ 12 ], sudut pantul [ 13 ], dan sudut bias [ 14 ] diukur terhadap garis normal bidang batas. Untuk gerak parabola sebuah proyektil sudut diukur terhadap arah mendatar ke sisi geraknya [ 15 ]. Dan untuk onggokan bahan butira, sudut repos (angle of repose) diukur terhadap arah mendatar dari sisi dalam bahan [ 16 ], yang dapat diukur menggunakan metode statis atau dinamis [ 17 ].

                                                                                                                                                                                                                                                                      system dynamics

                                                                                                                                                                                                                                                                      System dynamics (SD) adalah suatu metodologi berdasarkan sistem umpan-balik yang dipinjam dari teori kontrol, dan metodologi ini dapat dengan mudah menangani ketidaklinieran dan penundaan-waktu dan struktur multi-simpul dari suatu sistem yang kompleks dan dinamis [ 1 ]. Dalam pemodelan dengan system dynamics, variabel-variabel tidak langsung dikecualikan dari pertimbangan jika pengukuran tercatat tentang variabel-variabel ini kurang [ 2 ]. Penambahan kata sifat, berupa kata benda, pada frasa system dynamics, yang semula mencakup penerapan yang lebih luas [ 3 ], membuatnya memiliki arti yang lebih khusus dan terbatas seperti digunakan pada multibody system dynamics [ 4 ], engineering system dynamics [ 5 ], dan earth system dynamics [ 6 ]. Selain itu spesialiasi lebih jauh dari multibody system dynamics menghasilkan vehicle system dynamics [ 7 ], yang bahkan telah tersedia matakuliah khususnya [ 8 ]. Agar lebih tersosialisasikan tedapat pelatihan analisis kebijakan menggunakan pendekatan SD ini [ 9 ], yang visualisasinya telah terkamodasi dengan GUI [ 10 ].

                                                                                                                                                                                                                                                                      Dalam pemodelan berbasis agent atau agent-based modeling (ABM), suatu sistem dimodelkan sebagai kumpulan koleksi entitas autonomus yang dapat memberikan keputusan, yang disebut sebagai agen [ 1 ]. ABM merupakan suatu teknik simulasi bottom-up, di mana kita menganalisa suatu sistem, dengan mendefinisikan metrik tertentu, melalui agen-agent individual sistem yang berinteraksi satu sama lain [ 2 ], sehingga ABM ini dapat dikatakan sebagai model suatu sistem yang dipengaruhi oleh individual dari sistem tersebut [ 3 ]. Tanpa mengurangi kecanggihan yang terdapat pada ABM, salah satu kekurangan utamanya adalah ketidakmampuan untuk menggunakan serta mengintegrasikan data dalam membuat prediksi jangka pendek [ 4 ].

Penelusuran menunjukkan bahwa terdapat berbagai gambar ilustratif [ 2 , 3 , 4 , 5 ], semi-realistik [ 6 , 7 ], dan realistik karena dihitung menggunakan angka, akan tetapi pada bagian penjelasannya tetap menggunakan diagram yang kurang realistik [ 8 , 9 ].

Terdapat tiga bahan utama dalam kerja yaitu gaya, perpindahan, dan penyebab, sehingga saat gaya disebut melakukan kerja pada suatu obyek harus terjadi perpindahan dan gaya tersebut yang menyebabkannya [ 4 ]. Dengan demikian hal ini dapat menjelaskan terdapatnya definisi bahwa dalam fisika, kerja didefinisikan sebagai suatu gaya yang menyebabkan pergerakan atau perpindahan suatu obyek [ 5 ], akan tetapi perlu diingat bahwa kerja bukan gaya. Secara teknis, kerja diperoleh melalui perkalian skalar antara gaya melalui aljabar dan perpindahan atau integral lintasan perpindahan dengan gaya melalui kalkulus [ 6 ]. Selanjutnya ukuran kemampuan dari sesuatu untuk melakukan kerja disebut sebagai energi [ 7 ]. Kata work dalam bahasa Inggris, yang diberi lambang $W$, diterjemahkan menjadi kerja atau usaha [ 8 ].

Kemudian untuk hanya mengambil informasi audio dapat dirancang tombol kendali dengan iframe_api, API YouTube lainnya, yang cukup sederhana tampilannya [ 2 ], hanya sayangnya terdapat tautan yang tidak lagi bekerja untuk citra tombol tersebut. Bentuk panel kendali yang dilengkapi dengan tombol play, progress bar, dan pengaturan suara juga tersedia [ 3 ], akan tetapi belum berhasil dicoba. Selain itu terdapat cara lain yang menanamkan video dari YouTube dengan tag iframe dan kemudian membuat tag parent yang menutupi bagian videonya [ 4 ], di mana hal ini merupakan hal yang cerdik, akan tetapi hanya masih kurang bagaimana mengakses progress barnya. Untuk cara yang terakhir ini masih dapat dibantu dengan parameter-parameter yang disediakan oleh pemutar video YouTube yang ditanamkan pada suatu halaman web [ 5 ].

Hal ini mirip dengan saat kita melihat suatu benda di sekeliling kita secara langsung dibandingkan dengan setelah direkam oleh kamera dan dilihat melalui layar komputer. Terjadi perubahan koordinat dari dunia-ke-kerangka, yang untuk beberapa aplikasi juga dari kerangka-ke-dunia (frame-to-world) [ 2 ]. Penskalaan (scale) yang merupakan salah satu transformasi dasar [ 3 ], dapat menjelaskan hal tersebut. Salah satu aplikasi dalam transformasi Kartesian 2d yang bersifat konformal, afin, dan polinomial adalah mengubah proyeksi tidak diketahui menjadi suatu proyeksi yang diketahui [ 4 ], dengan implementasinya adalah dalam aplikasi untuk melakukan koreksi perspektif foto [ 5 ]. Penerapan yang lebih sederhana adalah bagaimana menggambarkan koordinat dunia (yang terlihat melalui suatu jendela) ke dalam koordinat komputer (yang terlihat melalui viewport suatu devais) [ 6 ] atau yang lebih sederhana lagi adalah saat melakukan konversi nilai temperatur dari suatu skala temperatur ke skala temperatur yang lain [ 7 ].

Di sini hanya akan diilustrasikan kurva tersebut dan kurva lainnya yang kurang tepat.

Pengunjung situs blog ini mulai pertengahan tahun 2011 dapat menggunakan akun Facebook atau Twitter untuk memberikan komentar yang kendali atas indentitas mana yang digunakan [ 2 ]. Khusus untuk Twitter, platform ini telah digunakan untuk membagi tulisan blog dan masih merupakan suatu platform populer untuk para pendidik sedunia, yang agar tulisan dapat terbagi lebih baik dapat memperhatikan beberapa tips [ 3 ]. Salah satu kelebihannya menggunakan Twitter ketimbang aplikasi pihak ketiga lainnya adalah pengunjung dapat berkomentar pada suatu blog seperti mereka melakukan tweet, menyertakan rekannya dengan memberi tag dalam tweet tersebut, dapat melakukan retween komentar untuk membuat yang lain melihat lalu bergabung, dan pengguna lain akan menerima notifikasi dalam aplikasi Twitter mereka [ 4 ]. Hal juga memperhatikan bahwa Twitter merupakan sesuatu yang telah digunakan oleh orang-orang, dengan lebih dari 330 juta pengguna aktif setiap bulannya, sehingga kemungkinan para pengunjung blog telah memikili akun pada platform tersebut [ 5 ]. Akan tetapi dalam penerapannya, sayangnya masih bergantung dari content management system yang digunakan [ 6 ].

Model ini terkait dengan titik sampel dua-dimensi dengan satu variabel bebas dan satu variabel terikat, yang secara konvensional menggunakan $x$ dan $y$ [ 2 ]. Kedua parameter dalam SLR dapat diestimasi menggunakan least square (LR), yang penurunannya perlu meggunakan kalkulus ataupun tidak [ 3 ]. LR yang merupakan prosedur matematika untuk mendapatkan kurva terbaik yang cocok untuk data yang diberikan, yang dilakukan dengan meminimumkan kuadrat dari offset atau residual dari titik data ke kurva, umumnya dicontohkan dengan model linier [ 4 ]. Dalam proses penentuan kedua parameter fungsi linier, bila digunakan kalkulus, langkah meminimumkan dilakukan dengan menggunakan turunan terhadap kedua parameter tersebut [ 5 ]. LS atau lebih tepatnya yang dimaksud adalah OLS, suatu ordinary LS [ 6 ], tak diragukan merupakan salah satu algoritma pembelajaran mesin yang fundamental [ 7 ]. Perlu ditekankan bahwa LR (SLR dalam hal ini dan LS merupakan dua hal yang berbeda akan tetapi sering disampaikan secara terkait sehingga kadang membingungkan [ 8 ].

Terdaat hal yang menarik mengenai sistem ini, yaitu bahwa tanda pada gaya pegas sering kali masih menjadi pertanyaan [ 3 ].

Kontanta numerik ini mendeskripsikan sifat elastik suatu bahan padatan saat mengalami penarikan atau penekanan hanya dalam satu arah, biasanya pada arah panjang atau dimensi yang paling besar dari suatu bahan, dan kadang disebut pula sebagai modulus elastisitas [ 2 ]. Modulus ini didefinsikan sebagai rasio dari tegangan tarik (tensile stress) dan regangan tarik [ 3 ]. Nilai modulus Young secara umum bernilai begitu besar sehingga tidak dinyatakan dalam pascal akan tetapi dalam gigapascal atau $\rm GPa$ [ 4 ], seperti dari sekitar $0.01 - 0.1 \ \rm GPa$ untuk karet dengan regangan kecil sampai $1220 \ \rm GPa$ untuk intan [ 5 ]. Penguran modulus elastik dapat dilakukan dengan menggunakan cara statis dan dinamis [ 6 ].

Konsep ini dapat disampaikan setelah membahas modulus elastik [ 3 ] atau sebelumnya [ 4 ], dengan jenis-jenis modulus elastik yang umum adalah modulus Young, modulus geser, dan modulus bulk [ 5 ]. Istilah modulus bulk kadang langsung digunakan, diterjemahkan menjadi modulus kompresi, curah, ataupun limbak [ 6 ].

Panas dapat ditransfer dari satu bagian sistem ke bagian lain melalui peristiwa konduksi, konveksi, radiasi, dan vaporisasi [ 2 ]. Masing-masing peristiwa memiliki mekanisme yang berbeda, seperti ada yang hanya melibatkan agitasi molekul, perpindahan partikel dalam sistem, keluarnya partikel dari sistem, atau tidak melibatkan partikel bahan.

Kegiatan ini dikenal sebagai eksperimen pengeboran kanon (cannon boring experiment) yang dapat mendidihkan air dengan panas yang dihasilkan dari gesekan terus-menerus saat mengebor kanon [ 2 ]. Secara umum panas didefinisikan sebagai aliran energy dari lingkungan ke sistem, dengan lingkungan dianggap sebagai suatu kolam panas (thermal bath) bertemperatur tertentu, di mana aliran energi ini dipandang berbeda dengan usaha karena energi dari usaha dapat dimanfaatkan akan tetapi tidak dengan panas [ 3 ] atau secara lebih sederhana dalah energy yang ditransfer ke atau dari suatu sistem termodinamika dengan mekanisme selain kerja termodinamika atau transfer materi [ 4 ], yang dapat berlangsung bila terdapat perbedaan temperatur antara dua hal [ 5 ], e.g. sistem dan lingkungan, sehingga dapat pula dikatakan sebagai energi termal yang ditransfer dari system yang lebih panas ke sistem yang lebih dingin, dengan kedua sistem berkontak [ 6 ]. Saat membahas termodinamika gas kadang panas tidak didefinisikan dengan jelas, melainkan langsung dikaitkan dengan kapasitas panas [ 7 ].

Dalam memecahkan suatu permasalahan fisika multi-konsep strategi “diketahui-ditanya” tidak bekerja dengan baik dikarenakan memiliki kelemahan dalam mengindentifikasikan variabel pada masing-masing bagian, padahal konsep masing-masing bagian terhubung satu sama lain dengan variabel yang tersembunyi, untuk itu diperlukan strategi sketsa pengetahuan [ 2 ]. Terdapat pendekatan berbeda yang dilakukan oleh pemula dan pakar dalam memecahkan permasalahan fisika, di mana yang pertama akan mencari persamaan yang cocok dengan variabel-variabel yang diberikan atau mencoba memecahkannya dengan solusi dari persoalan yang mirip yang perlu dikerjakannya yang sayangnya pendekatan ini tidak universal, sedangkan yang kedua mampu untuk menerapkan berbagai konsep fisika yang diketahui, melakukan kombinasi konsep-konsep tersebut, sehingga dapat menangani bahkan permasalahan yang baru dan unik [ 3 ]. Contoh-contoh yang ada misalnya adalah balok terdorong pegas mendaki bidang miring sampai puncaknya, melayang membentuk gerak parabola, dan sampai pada daerah lain setelah melewati lekukan [ 4 ], pelontar pegas untuk melambungkan bola[ 1 ], dan mengapa kapal bisa mengapung, torsi pada derek saat mengangkat kapal, suara peluit kapal-kapal yang bersuperposisi, dan siklus mesin kapal yang mengada-ada [ 5 ]. Walaupun belum digunakan istilah permasalahan fisika multi-konsep, Pembelajaran Berbasis Riset (Research Based Learning-RBL), yang dilakukan sejak tahun 2006 sampai sekarang, merupakan suatu kegiatan mandiri yang dilakukan peserta ajar untuk memecahkan masalah dengan menggunakan berbagai konsep dan prinsip fisika [ 6 ].

                                                                                                                                                                                                                                                                        Untuk gas kapasitas kalor molar adalah panas yang dibutuhkan untuk menaikkan temperatur satu mol gas sebesar satu kelvin [ 1 ], yang terdiri dari kapasitas panas pada tekanan tetap dan pada volume tetap, di mana yang pertama selalu lebih besar dari yang kedua [ 2 ]. Nilai kapasitas kalor molar ini berbeda-beda untuk gas ideal monoatomik, diatomik, dan poliatomik [ 3 ].

                                                                                                                                                                                                                                                                        internal energy

                                                                                                                                                                                                                                                                        Energi dalam atau energi internal suatu gas ideal merupakan fungsi dari temperatur saja [ 1 ], sehingga merupakan suatu variabel keadaan [ 2 ]. Energi dalam suatu gas adalah jumlah energi kinetik partikel-partikel dalam gas [ 3 ] dan juga energi potensialnya, yang untuk gas ideal diabaikan karena tidak ada interaksi inter-partikel [ 4 ]. Energi dalam dapat dituliskan dalam tiga besaran ekstensif, yaitu entropi, volume, dan massa [ 5 ].

                                                                                                                                                                                                                                                                        mass

                                                                                                                                                                                                                                                                        Definisi mengenai massa sering terlihat berputar-putar karena massa merupakan suatu besaran fundamental yang sulit untuk didefinisikan dalam suatu istilah menggunakan istilah lain [ 1 ], yang dalam fisika merupakan ukuran dari inersia yang merupakan keengganan suatu benda untuk berubah kecepatannya atau posisi saat gaya diterapkan padanya [ 2 ]. Selain itu massa juga menentukan kekuatan gaya tarik gravitasinya terhadap benda lain [ 3 ]. Satuan massa adalah kilogram dan telah dilakukan definisi ulang, sebagaimana pula untuk satuan besaran-besaran lainnya, dengan menggunakan tujuh tetapan, di mana definisi terevisi massa dipilih untuk memperbaiki nilai numerik tetapan Planck $h$ [ 4 ]. Dalam keseharian istilah massa dan berat sering digunakan untuk hal yang sama, akan tetapi keduanya tidak memiliki arti yang sama dalam fisika [ 5 ]. Sedangkan dalam kimia massa merupakan ukuran jumlah materi yang terkandung dalam suatu benda [ 6 ].

                                                                                                                                                                                                                                                                        special processes

                                                                                                                                                                                                                                                                        Untuk gas ideal dalam sistem tertutup terdapat empat proses spesial yang sering dibahas, yaitu isotermal, isobarik, isokhorik, dan adiabatik yang semuanya bersifat reversibel [ 1 ], dengan telah terdapat visualisasi untuk ketiga proses pertama [ 2 ]. Selain itu terdapat pula proses throttling yang tak-reversibel dan proses politropik [ 3 ], yang pada awalnya istilah terakhir ini digunakan untuk semua proses reversibel pada sistem tertutup ataupun terbuka bagi gas atau uap yang melibatkan baik transfer panas maupun kerja, sedemikian rupa sehingga kombinasi spesifik sifat-sifat gas bernilai tetap selama proses ini [ 4 ].

                                                                                                                                                                                                                                                                        state, process, cyle

                                                                                                                                                                                                                                                                        Pada suatu gas yang merupakan suatu sistem, terdapat keadaan, proses, dan siklus [ 1 ], dengan keadaan yang dimaksud adalah suatu keadaan termodinamika [ 2 ]. Keadaan ini dispesifikasian oleh berbagai variabel keadaan [ 3 , 4 ]. Untuk saat ini pembahasan dibatasi hanya untuk gas ideal.

                                                                                                                                                                                                                                                                        ideal gas law

                                                                                                                                                                                                                                                                        Gas ideal mematuhi persamaan

                                                                                                                                                                                                                                                                        ideal gas law

                                                                                                                                                                                                                                                                        Hukum gas ideal, yang adalah persamaan keadaan suatu gas ideal hipotetikal, merupakan suatu pendekatan yang baik untuk banyak jenis gas dalam berbagai keadaan akan tetapi dengan berbagai keterbatasan [ 1 ]. Gas riil akan mendekati kelakukan gas ideal pada keadaan dengan kerapatan dan tekanan cukup rendah dengan temperatur cukup tinggi, sehingga energi kinetik molekul-molekul gas dapat mengatasi gaya-gaya antar molekul [ 2 ], yang dalam keadaan ini semua energi dalam berbentuk energi kinetik dan semua perubahan energi dalam diikuti dengan perubahan temperatur [ 3 ]. Atau dengan kata lain temperatur sebenarnya merupakan suatu ukuran dari energi kinetik rata-rata molekul-molekul suatu gas ideal [ 4 ]. Terdapat hukum-hukum sederhana gas, yaitu hukum Boyle, hukum Charles, dan hukum Avogadro, yang apabila dikombinasikan akan menghasilkan hukum gas ideal [ 5 ]. Ada dua cara menuliskan hukum ini, yaitu sebagai persamaan termodinamika fungsional atau termodinamika statistik [ 6 ].

                                                                                                                                                                                                                                                                        kinetic theory of gases

                                                                                                                                                                                                                                                                        Gas dapat dipelajari melalui aksi skala kecil dari setiap individu molekul atau melalui aksi skala besar gas secara keseluruhan, di mana untuk aksi skala besar pengukuran dapat dilakukan, akan tetapi untuk aksi skala kecil perlu menggunakan model teoretis, yang disebut TKG atau teori kinetik gas [ 1 ]. TKG ini didasarkan pada gambaran mengenai bahan secara molekuler [ 2 ]. Terdapat tiga [ 3 ], empat [ 4 ], atau lima [ 5 ] asumi yang digunakan dalam merumuskan teori ini.

                                                                                                                                                                                                                                                                        pressure

                                                                                                                                                                                                                                                                        Tekanan didefinisikan sebagai gaya per satuan luas [ 1 ] atau lebih tepatnya gaya yang tegak lurus dengan permukaan per satuan luas permukaan tersebut [ 2 ]. Tekanan merupakan suatu besaran skalar, yang menghubungkan antara vektor elemen luas dengan gaya normal yang bekerja padanya, sehingga dapat dikatakan sebagai konstanta kesebandingan yang menghubungkan kedua vektor normal tersebut [ 3 ]. Selain dapat menjelaskan bahwa benda yang lebih kecil luas permukaannya, seperti paku dapat lebih mudah masuk ke dalam dinding dibandingkan dengan benda yang lebih luas permukaannya saat digunakan gaya yang sama [ 4 ], tekanan merupakan konsep kunci untuk mekanika fluida, digunakan dalam hukum gas ideal untuk menjelaskan energi gas, dan dimanfaatkan dalam banyak hal-hal lain [ 5 ].

                                                                                                                                                                                                                                                                        kinetic energy

                                                                                                                                                                                                                                                                        Suatu bentuk energi yang dimiliki benda karena geraknya disebut sebagai energi kinetik [ 1 ]. Terdapat berbagai jenis energi kinetik, seperti energi kinetik vibrasi, rotasi, dan translasi [ 2 ], dengan bentuk yang terakhir yang akan dibahas di sini. Mungkin sifat yang paling penting dari energi kinetik adalah kemampuannya untuk melakukan kerja [ 3 ], yang apabila dilakukan pada benda lain terjadi melalui peristiwa tumbukan [ 4 ].

                                                                                                                                                                                                                                                                        impulse

                                                                                                                                                                                                                                                                        Impuls merupakan perkalian dari nilai rata-rata gaya dan rentang waktu selama gaya tersebut bekerja atau perubahan momentum yang dihasilkan gaya tersebut [ 1 ], atau lebih umum merupakan integral dari gaya selama selang waktu bekerjanya gaya tersebut [ 2 ]. Penggunaan utama dari konsep ini adalah untuk mempelajari gaya impak rata-rata selama tumbukan, dikarenakan massa dan perubahan kecepatan umumnya diukur akan tetapi kecepatan selama tumbukan tidak [ 3 ].

                                                                                                                                                                                                                                                                        conservation of momentum

                                                                                                                                                                                                                                                                        Momentum merupakan suatu besaran yang kekal, yang dalam suatu sistem tertutup total momentum bernilai tetap, di mana prinsip ini dikenal sebagai hukum kekekalan momentum atau kekalan momentum [ 1 ], yang merupakan bagian dari berbagai hukum-hukum kekekalan dalam fisika [ 2 ]. Perlu disadari bahwa momentum kekal dalam tumbukan, ledakan, dan peristiwa lain yang melibatkan banyak benda, di mana kekal berarti besaran itu, yang dalam hal ini adalah momentum selalu bernilai tetap selama suatu peristiwa berlangsung [ 3 ]. Kekekalan momentum juga digunakan dalam fluida, misalnya pada perumusan aliran tunak 1d [ 4 ]. Dalam pembelajaran hukum kekalan ini dapat diamati melalui eksperimen menggunakan linear air track dengan analisis citra gerak bendanya [ 5 ].

Besaran ini terkait dengan hukum II Newton dan merupakan besaran vektor [ 3 ], yang merupakan hasil perkalian dari besaran skalar massa dan besaran vektor kecepatan [ 4 ]. Momentum yang dimaksud di sini lebih tepatnya disebut sebagai momentum linier.

Lebih tepatnya tidak ada gaya yang terisolasi, sehingga untuk setiap gaya luar yang bekerja pada suatu benda, ada gaya dengan besar sama tapi arah berlawanan yang bertindak balik pada benda lain penyebab gaya luar tersebut [ 3 ]. Hukum ini dirujuk pula sebagai hukum aksi-reaksi dan masih menjadi kajian yang menarik belum lama ini [ 4 ].

Salah satu yang sering menjadi sumber permasalah dalam memahami hukum ini adalah suku $F = ma$ dianggap sebagai suatu gaya dan bukan jumlah gaya-gaya [ 2 ].

Hukum-hukum ini telah terverifikasi melalui eksperimen dan observasi lebih dari 200 tahun dan merupakan pendekatan yang amat baik untuk skala dan laju sehari-hari [ 3 ]. Pada abad ke-20 hukum-hukum Newton ini digantikan sebagai hukum-hukum fisika yang paling mendasar oleh mekanika kuantum dan relativitas [ 4 ].

Untuk penerapannya, gerak pendulum dalam lintasan lingkaran vertikal dan roller coaster merupakan contoh-contoh GMBB [ 3 ].

Pada gerak melingkar dengan laju tetap ini, dapat diturunkan percepatan sentripetal [ 2 ], yang merupakan percepatan yang mengarah ke pusat lintasan lingkaran [ 3 ]. Percepatan ini disebabkan oleh jumlah gaya yang mengarah ke arah yang sama [ 4 ].

Atau langsung dengan perumusannya akan tetapi masih menyembunyikan dimensi ketiganya, yang muncul saat perlu mendefinisikan perkalian silang dua buah vektor [ 2 ]. Mengaitkannya langsung dengan koordinat silinder merupakan alternatif lain, di mana simbol yang digunakan telah $\phi$ alih-alih $\theta$ [ 3 ], sehingga akan memudahkan transisi dari sistem koordinat 2d ke 3d. Dalam sistem koordinat polar ini fungsi untuk menggambarkan kurva-kurva akan memiliki bentuk berbeda dengan dalam sistem koordinat Kartesius [ 4 ].

Sebagai suatu eksperimen, untuk membuktikan prediksi teori, menembak monyet merupakan aplikasi gerak parabola yang menarik [ 4 ] dan terdapat pula contoh tayangannya [ 5 ].

Yang termasuk dalam kinematika 2d adalah rangkaian beberapa gerak lurus pada arah tegak lurus yang membentuk gerak zigzag, superposisi dua gerak lurus pada arah saling tegak lurus, dan gerak parabola [ 2 ], serta ada pula yang menambahkan gerak pada bidang miring dan gerak melingkar [ 3 ]. Mungkin pula dapat ditambahkan gerak yang membentuk kurva Lissajous [ 4 ].

Atau benda akan menanggapinya dengan bergerak dengan kedua pengaruh tersebut yang saling terjumlahkan, seperti gerak menggelinding merupakan penjumlahan dari gerak rotasi dan translasi [ 2 ]. Contoh lain pemanfaatan prinsip superposisi dalam mekanika adalah gerak perahu menyeberangi sungai [ 3 ] dan gerak parabola [ 4 ]. Dalam gelombang prinsip ini mengatakan bahwa bila dua atau lebih gelombang melewati suatu titik, perpindahan pada titik tersebut adalah penjumlahan dari perpindahan dari masing-masing gelombang, yang digunakan untuk interferensi dan pelayangan pada bunyi [ 5 ] dan interferensi dan difraksi pada cahaya [ 6 ]. Untuk gelombang bunyi terdapat batasan penggunakan principle superposisi, seperti tidak dapat digunakan untuk gelombang yang amat besar dan gelombang kejut [ 7 ].

Eksperimen untuk mengamati GJB harus dilakukan dalam lingkungan vakum agar hambatan udara tidak mempengaruhi hasil, yang untuk benda-benda kecil dan halus permukaannya sampai suatu massa jenis tertentu eksperimen masih dapat dilakukan dengan adanya udara [ 2 ]. Sebenarnya suatu GJB dapat lebih umum, di mana benda tidak harus bergerak hanya ke bawah, dengan benda yang bergerak ke atas pun dalam termasuk dalam GJB selama hanya gaya gravitasi yang bekerja padanya [ 3 ], sehingga dapat melingkupi gerak benda-benda langit [ 4 ]. Saat ini hanya dibahas mengenai gerak dekat dengan permukaan bumi sehingga percepatan gravitasi dapat dianggap konstan.

Terdapat pula nama lainnya yaitu gerak lurus dengan percepatan [ 4 ].

Kendaraan yang berada di belakang harus memiliki kecepatan tetap lebih besar dari kecepatan tetap kendaraan yang berada di depan. Umumnya pada permasalah pengejaran dua kendaraan, kendaran yang mengejar memiliki percepatan [ 4 ].

Dengan demikian gerak lurus beraturan atau GLB merupakan gerak benda mengikuti lintasan lurus dengan kecepatan tetap atau beraturan atau seragam [ 1 ]. GLB ini merupakan salah satu bagian dari gerak lurus, di mana bagian lainnya adalah gerak lurus dengan percepatan berubah [ 2 ].

Persamaan-persamaan ini dibatasi untuk digunakan hanya pada kasus gerak lurus dalam 1d dengan percepatan tetap.

Selain itu terdapat pula permasalahan yang melibatkan kecepatan arus sungai yang bergantung posisi sehingga agak tidak nyata [ 7 ] dibandingkan dengan kecepatan arus sungai pada umumnya [ 8 ]. Kemudian, penyelesaian dengan langkah-langkah terstruktur [ 3 ] menggelitik untuk dikaji lebih lanjut dalam mendukung pembelajaran yang lebih efektif dan efisien.

Dapat pula dipandang sebagai kecepatan suatu obyek relatif terhadap obyek lain, yang merupakan kecepatan obyek pertama menurut pengamat yang bergerak bersama-sama dengan obyek kedua [ 2 ]. Dalam teknis perhitungannya diperlukan kemampuan penjumlahan vektor dan cara berpikir bahwa satu kerangka acuan merupakan perantara adalah satu pendekatan yang amat berguna [ 3 ], di mana pendekatan ini memerlukan pemahaman pemanfaatan indeks bawah [ 4 ], yang kadang dituliskan pula dengan notasi berbeda [ 5 ].

Dan kadang tidak dijelaskan kecuali merupakan besaran skalar, akan tetapi langsung pada istilah laju sesaat dan laju rata-rata [ 4 ]. Di sini akan digunakan dengan arti sebagai besar dari kecepatan (atau kecepatan sesaat).

Sebagaimana kecepatan satu dari kecepatan rata-rata adalah $\rm m/s$ dan kecepatan rata-rata merupakan besaran vektor.

Akan tetapi terdapat pula penggunaan istilah gerak konsekutif [ 2 ].

Salah satu pendekatan untuk membantu pemahaman dilakukan dengan memanfaatkan alat bantu microcomputer based laborator atau MBL [ 3 ]. Dan untuk menyelamai lebih dalam, pengamatan pergerakan mata saat peserta mengerjakan tes terkait materi ini pun dilakukan [ 4 ]. Hal ini menunjukkan pentingnya peran grafik kinematika dalam fisika. Gerak lurus dengan percepatan yang merupakan fungsi waktu dapat pula dianalisis menggunakan grafik selain dengan kalkulus [ 5 ]. Kemudahan menggambarkan grafik pun telah banyak tersedia secara daring, walau masih dengan variabel dummy $y - x$ [ 6 ].

Kerangka acuan yang digunakan dalam dinamika dikenal pula sebagai sistem koordinat, dengan sumbu-sumbunya bersumber dari suatu titik yang disebut origin [ 2 ].

                                                                                                                                                                                                                                                                        not unique

Bila kerangka acuan tidak unik dan dapat dipilih, dengan memperhatikan bahwa kerangka acuan yang dipilih sebaiknya memudahkan pemecahanan permasalahan, maka posisi suatu benda juga akan menjadi tidak unik karena bergantung pada kerangka acuan dari mana posisi benda dideskripsikan.

Prefiks ini dikenal juga sebagai prefiks metrik, di mana semua prefiks metriks saat ini merupakan dekadik [ 4 ].

                                                                                                                                                                                                                                                                        unit conversion

Dalam era internat saat ini terdapat banyak aplikasi daring untuk melakukan konversi satuan, dari yang langsung menampilkan besaran-besaran yang dapat dikonversi [ 7 , 8 , 9 ], sampai yang pengguna perlu terlebih dahulu memilih kategori satuan yang akan dikonversinya [ 10 , 11 ].

Secara keseluruhan terdapat 7 satuan dasar SI yang membentuk 22 satuan turunan lainnya dengan nama dan lambang khusus [ 2 ]. Selanjutnya, definisi satuan dasar telah beberapa kali diubah sejak Konvensi Metre pada 1875 dan pada 20 May 2019 diperkenalkan definisi baru, menggantikan definisi sebelumnya [ 3 ]. Pengubahan ini menyatakan bahwa setiap satuan dasar SI didefinisikan oleh suatu rujukan yang disepakati yang telah tersedia dan secara mudah direalisasikan secara eksperiment oleh siapa saja, di mana saja, kapan saja, dengan presisi yang cukup baik (ketidakpastian pengukuran yang rendah) untuk kebutuhan kita [ 4 ]. Rujukan yang dimaksud adalah tujuh nilai yang mendasari SI yang telah diperbarui, yang diyakini memiliki nilai yang sama di mana pun di alam semesta ini dan dinyatakan dalam bentuk tujuh konstanta [ 5 ].

Further reading will explain vector as element of vector space [ 4 , 5 ]. Here we will require only the simple definition of a vector. Vector can be drawn using a directed line segment [ 6 ]. Two examples about vector, which differs it from scalar, are displacement compared to distance and velocity compared to speed [ 7 ].

Demikianlah bunyi undangan yang saya terima dari Kaprodi Fisika Abdul Waris.

Alhamdulillah waktunya dapat disesuaikan dengan aktivitas yang ada pada hari itu, dua hari yang lalu tersebut. Dalam acara ini saya menceritakan hal-hal yang saya lakukan dahulu saat masih seperti para pendengar, menjadi asisten, aktif di unit kegiatan, ikut himpunan, dan sebagainya. Beberapa pertanyaan diajukan oleh para pendengar setelah cerita-cerita diberitakan.

Dari ceritanya, anak harus diamati pada saat ia sudah cukup umur, jumlah kata-kata yang dapat diucapkannya. Kalau tidak salah anak berumur kira-kira 2-3 tahun itu harus telah dapat mengucapkan 80 kata atau lebih. Beberapa hari kemudian, kata-kata yang diucapkan Adik dihitung dan dicatat. Alhamdulillah ada 133 kata lebih.

Akan tetapi dokter optimis bahwa tren hasil pemeriksaan menuju ke arah normal (penyembuhan).

Bila berada dalam rentang tersebut maka dikatakan telah pulih sepenuhnya.

Istilah ‘sebenarnya’ yang sering menggantikan kata ‘proper’ tidak digunakan di sini agar tidak membingungkan.

                                                                                                                                                                                                                                                                        Waktu proper dapat ditentukan dengan mudah bila konsep ruang waktu diperhatikan kembali. Pengamat yang mengamati dua peristiwa dengan menggunakan jam yang sama akan mencatat waktu proper (lebih tepatnya selang waktu proper).

Apakah ada yang istimewa dengan hal ini? Tentu saja ada dan hal tersebut adalah apa yang menyebabkan bola yang menggelinding itu berhenti. Orang bisa mengatakan bahwa penyebabnya adalah gesekan, akan tetapi bagi orang yang telah belajar gerak rotasi, dengan asumsi bola menggelinding tanpa tergelincir, hanya gesekan statis yang berperan dalam kasus ini. Dan gesekan statis tidak menyebabkan bola kehilangan energi kinetik sehingga dapat berhenti, malah arah torsi yang ditimbulkan gesekan statis ini seharusnya menyebabkan bola menggelinding bertambah cepat.

Mengapa sampai mereka mati? Hal ini pun terjadi dalam wadah yang tidak berisikan air yang manis melainkan juga air tawar saja. Hal ini pernah diperhatikan penulis dan tidak menjadi suatu tanda tanya sampai pada suatu hari penulis mendapati semut-semut yang belum mati melainkan berputar-putar di sekitar tepian air berulang-ulang (Bandung, 2008).

                                                                                                                                                                                                                                                                        miskonsepsi dalam fisika

                                                                                                                                                                                                                                                                        Angelina Jolie dalam film Wanted (2008) dapat menembakan peluru pistolnya menempuh lintasan melengkung, mirip lintasan peluru meriam yang berbentuk parabola secara vertikal, akan tetapi dalam hal ini lintasan peluru pistolnya melengkung secara horisontal. Apa yang salah di sana? Bagi yang telah belajar fisika tentu akan muncul banyak pertanyaan akan tetapi bagi yang tidak, hal ini cukup menarik sekedar sebagai hiburan. Mungkin suatu saat film tersebut akan masuk dalam daftar yang dicakup oleh buku dengan judul Insultingly Stupid Movie Physics: Hollywood’s Best Mistakes, Goofs and Flat-Out Destructions of the Basic Laws of the Universe karangan Tom Rogers (Sourcebooks Hysteria, 2007), yang rasanya tidak perlu dijelaskan kira-kira apa isinya, yang telah cukup jelas tercermin dari judul buku tersebut.
